How to install Deatschwerks DW400 Fuel Pump for Mustangs! | Horsepower United

- When one of the owners of The Fuel House wanted to swap his ProCharger supercharged 2018 Mustang GT to E85, he knew it was going to need more fuel pump.
We snagged a DW400 pump after talking to the guys at Deatschwerks and figured why not make a video of the install.
The install was really straightforward and took about 2hrs total since we were joking around and filming. I am sure someone that was a bit more professional than us could do it in about 1 hour.

Dude hands down you got it detail by detail. Thank you!!!
You are very welcome!
@@erikradzins jajajajajajaja would it work on a 2010
@@loschenes5357 I am sure they have something for that.
I used this step by step for the 2014 S197 and this went great. Thank you!
Very welcome!
Awesome instructions, just replaced my 14 gt fuel pump with DW400 part 9-401-1046.
I installed a DW 400 in my procharged 2013 mustang gt and went E85 remotely tuned by Blow by Racing. I’m very happy with it.
Awesome man, thanks for the feedback. :)
13SS LOL how much boost are you running with this dw400? I’m thinking of doing this instead of a return style. Trying to keep the power in the “safe” gen1 range so a fuel system won’t be ideal yet for the power I need
Force Fed Coyote Sorry for late response I’m at 10psi at 7k on E70 and jms powermax boost pump with safe fuel trims.
dusty No starting problem at all and new sock just presses on bottom.
13SS LOL thanks I figured it out after looking, it didn’t really press on, I trimmed the little tiny tabs to push it on better
Thanks Erik !
Keep em coming
This is so helpful. Thank you so much!
Love hearing that!
2 out of 10 for you which is 4 out of 10 for me. 😁 thanks great video
Good morning, I wanted to ask how many psi the fuel regulator goes for my 2003 4.6 mustang. It has a high compression fuel pump and 24lb injectors but I don't know how many psi to set the fuel pressure regulator.
Good video, but you skipped one of the important parts! After you cut the piece where the pump goes in, you didn't show how it was held in place ,how it was oriented, etc. these details cost a LOT of time if not familiar with it. Other than that GOOD video!
Great video.
Awesome video man, it was very informative. I got 2 questions, first did your car smell like gas after finishing this and if so how long did it last? Second did u have to upgrade your fuel lines too or were the stock ones big enough for the DW400?
If you spilled fuel it will for a little bit. Just be careful not to drip any on the carpet, cause that will smell as well.
So glad you made this video was having a hard time finding one. Getting ready to go e85 and wanted to do the pump myself. Thanks!
Thanks man!!! I hope to do more simple videos like this
Just finished mine yesterday hopefully I get my procharger 3.7 done today. Project keeps getting pushed back
Hi Saw your video and looks straight forward. I'm looking at going to E85 on a 2013 GT with an Edelbrock Eforce pushing 10 psi boost. I've been told a return style fuel system, Id1050X injectors and tune will be required. I see you are installing this on a procharger app. I wondering if this should be enough for my application
Will you recommend changing the fuel lines, and injectors rail as well? Or just the pump and the injectors? Thank you for your response
Were you running the BAP with the dw400 on e85?
Any tuning needed or other upgrades such as fuel lines etc or is stock all good? got a slightly modified 5.0.. also running regulator gas atm
I’ve got a sai li return style fuel system and I ordered 2 of the dw400 fuel pumps and the pump you’re showing has the siphon spot on it and the 2 pumps I ordered do not have the siphon spot on it and I will not be able to use them and your video does not show what plug and play kit exactly needed to order, the link in the description only goes to their main website I cannot find those pumps whatsoever
This video is really old, so I am sure they changed the link. I would call DW directly they are great people.
Thank you sir
nice video :)
Hey Erik, getting a Procharger soon for my 2017 Mustang V6. if I have a Procharger running a 3.85 pulley, 52# Injectors on 91, do I need a DW400!? I have longtubes, highflow cats, 73mm throttle body and ported intake manifolds.
If you ever wanna run E85 you will want to have a big fuel pump. :)
Erik Radzins no E85 close stations. Also it’s only e54 here. So I think I’ll be good.
Erik Radzins one last question. Is the P1X overkill for a 2017 V6 Mustang? It’s my understanding that it will flow better and have less parasitic drain than the P1SC1. Also what pulley would it come with?
what exactly is the purpose of the fuel sending unit on the passenger side of the gas tank? I have already replaced the fuel pump but still having spratic fuel issues. I have a 2012 mustang v6
Do you know the size of the feed line? My twin dw300 fuel pumps didn't come with any extra fuel lines for the fuel pump for 07-10 mustang gt 500 thanks
Do you still need a boost a pump when using this pump on a supercharged car
If you're going over 600hp to the wheels then get a boost a pump.
Hey man I’m having issues with my pump it’s not sending fuel to the engine. I’ve tried seeing if the connector is sending power to the pump which it is. I took off the test tube cranked the car over and wasn’t getting any fuel to the motor, the car only has 13k miles how can this fuel pump already go bad it’s only been driven on the weekends
Can I install this pump in a stock 18 mustang gt? Does it need a tune? I am doing headers and ported
No tune if its just a pump swap. you need the tune for the headers and intake though,
Did it blow up after not putting in a return style fuel system ?
Awesome channel man!! So I can do this on my 17 roush and run E85? Car makes around 750 now on 109 race fuel I also have a VMP BAP I guess all that will still work with this?!
17ROUSH sam my guess is yes. I’ll be doing this as well just need to get with a tuner that will tune a boosted application without a fuel system. I would keep it under 750whp with just a bap and dw400
Just how are you supposed to get the filter sock on the DW pump?
They supply a new sock, and it just goes on the same way the stock one does. Slip fit.
It's definitely a tight fit I tapped it in with a hammer lol
Is it normal to smell gas inside the vehicle after installing this DW400? (SC GT 17)
Nope, sounds like you might not have the tank ring all the way seated.
Did you feel any difference after install this in your supercharger mustang? And what sc you have?
@@raga1s The factory pump I think around 275-285 Lph not sure but the Dw400 was quick plug n play sit-up with the 1000cc is enough to put around 700 rwhp without bap if considering bap definitely would be more room to push. At the moment running TVS 2650 from HARROP down in Australia, 683 rwhp on pump 98 Ron
No need to drill holes in the bottom of the bucket?
How in the wold did you install the bezel back into the groove? I’m having a hard time. Been smaking the hell out of it and nothing. You make it look way to easy
Have someone push down on the pump lid... then pound the ring around. :) Then its easy as pie!
Just a word of caution; if you're using a metal screwdriver to chisel the ring off and on it can produce sparks which is not ideal when working around fuel vapors. It would be better to use a brass punch as your chisel device.
How much power did u put down with the pump I jst ordered mine along with dw95s
I broke my clip to the line that clips in the bottom you know or have a part number for that clip
I have a 2011 GT putting 500hp to the wheels with a supercharger. Eventually I want to bump that up to around 650 on 93 pump gas. My fuel pump went out and was wondering what fuel pump would you reccomend for 600+ whp?
Send DW a message and see what part number they got for you. Otherwise the stock pump with something like a VooDoo booster will get ya there
Is this DeatschWerks pump still running strong, with no issues?
Would assume, but the car was sold years ago...
Must not be the same for a 14
Did you feel any difference with the performance after the kit
Kept up with the power the supercharger made :)
Can someone tell me what is the purpose of the siphon line is and if it needed? I am trying to install a walbro 525 but it does not have a anywhere to connect it to.
If you don't connect that line, you will only get 1/2 tank of fuel. you have to have the siphon line, to get fuel from the other tank.
@@erikradzins thank you taking the time to reply
Not wise folks to run e85 on a none return style fuel system. FYI
can you explain? im actually curious
How did you get the sock filter on the pump? Mine will not fit onto the inlet.
What year do u have
@@andrewgarcia4379 2014
I got it to clip on. It was just hard to snap on. Did you get any lights on your dash when you bypassed the oem regulator hose routing? I do have the blank, just wasn't sure whether or not to keep the oem regulator hose routing within the hanger.
do you need a retune for this pump?
I have a roush kit on my 17 gt and I’m making about 680whp but u want to run e85 and turn up the boost 750+WHP - 800+WHP will this dw400 & fic 1000s get me up there or will I need a fuel system?
800 wheel, you should be looking for a full fuel system.
Erik Radzins fuckk I was trying to budget build lol
Stock Fuel Rails? which injectors? looking for similar power (800+)
Deatschwerks 95lb 1000cc injectors
BTW the pump does not work for 2011-2014 Mustang. Those years require 9-403-1046, not the 9-403-147 that fits 2015-2018.
Different part numbers yes... but the same "pump" and basically same install.
It is the same pump body, but they are not interchangeable. The s197 pump will not work on a s550. S550 will not work on a s197. Go to DWs website if you don't believe me. Pretty easy to see the different fittings on the top of the pump.
I understand that... I meant that they have these pumps for the entire line up. (not meaning the exact same part number) sorry for the confusion.
@@erikradzins the older pump doesn't have a syphon line on top of the pump,so I m not sure if there is a way to still install it
@@josevelez1387 interesting!
What size of injectors are you using in that mustang?
Stock actually. It had 95's in it, but took them out cause it didn't need them.
I am having starting issues DW mentioned something about a check valve but where do I install it? Other than that the car runs fine.
So I can run E85 with boost using that pump and injectors ? , I have a twin turbo 2018 5.0 but currently pushing 696 to the wheels using 93 octane was wondering if I need to go all out and buy an expensive fuel system or I can do it with this pumps and a Booster
I talked to Palm Beach dyno about it they said they can tune my Vortech kit on my 2018 gt with this pump and id injectors on e85 . Hit them up and let me know what you go with because I’m about to order that set up soon .
Of course paired with my Vortech bap
Native Shift I’m gonna see what they say , I sent them an email , I was thinking of Sai Lai but if this works I wouldn’t mind getting it
TheLoneWolf11 did u ever hit them up ?
Native Shift I emailed LPF & Lund both recommend me to get Fore innovation , lethal performance or Sai Li
Installed the pump in my '12 GT with a VMP Gen 3 blower. Fueled up with true e85. Guess what. Pump will not support my engine. Tried it without my JMS bap. Ran out of fuel. Hooked up said bap. Turned it all the way up to 21 VDC and still ran out of fuel. Looks like I will back my fuel down to e65 or so. Heck my '17 pump with the JMS had enough fuel at e54. May just go dual GT500 pump and be done with it.
You may have a kinked hose, leak, or restriction. I don't know what power level you were at, but I have personally done mid 700's now on E85 with it. I thought MAK performance made 800 wheel, but you would have to ask them. I run my JMS at the 18v setting.
I may in fact have a defective pump per DW. It will blow a 30 amp fuse. I had to rig a 40 amp. I should be at 800whp.
Joe D it wasn’t supporting at 800whp?im trying to do this set up to reach 680ish whp
should have shown connecting the wires back up kinda of a big step haha
It just plugged in, so wasn't much to show. But yes. :)
You mean destructions?
My car does not start and I’ve done absolutely everything mentioned on that video
Qq
Hey Erik i had this pump installed by a shop and running my procharged 2015 mustang gt on e85 now. The problem i'm having is the car is struggling to start despite me cycling the car in the on position...it does always start but has to crank alot longer than i prefer...is that normal with these?
Nevin Barley You shouldn’t have trouble starting, might want to check work done.
@@Pistol755 install is on point. I believe we've determined that a check valve is needed. Does anyone have any information of how they implemented a check valve for the dw400 in the mustang?
Nevin Barley I’m sure if you call DW they will insure you that a check valve shouldn’t be needed with there pump.
@@Pistol755 thanks and i Just spoke with Mark at deatschwerks. It turns out some cars work fine and some cars do have the hard starting issue. He said they are working on a new pump with a check valve built in but said i could add a russell check valve on the outlet line; that would just require cutting up the factory lines.
Nevin Barley Ok cool hope it works for you.
A good tip is not to have a freaking light next to your fuel tank while removing the pump .. it can catch on fire ... Big no no
Its a sealed LED.... but thank you. :)
Not that easy...
Would this be the same process as my 2010 gt?
Can I run this pump with my boost a pump and run E85 looking for 700hp rwhp
I did. :)
My fuel pump went out as soon as I let the gas station when filling up lmao
Does this pump work with 2018 Ecoboost Mustangs ?
Can you use this fuel pump on a NA 2018 mustang Gt ?
Is a tune required when upgrading to this fuel pump?
Not if you aren't changing anything else.
