Holy hell you saved me with that check valve thank you so much I didn't even know it was there. I cleaned it out when I changed out a fuel pump couldn't figure out why when I shut off the engine 10 mins later I had to reprime the system watch this video went back to where I dumped the fuel and sitting in the screen was my ball you saved my ass thank you. I will definitely send money to you best advise video I could of watched.
You have done an EXCELLENT job of explaining this fuel pump. Forced to use ether in one of my trucks for more than a year. And I know that ether starting is a MAJOR sin. Now,,, I can trouble shoot and know what I am looking for. Mechanics that I have asked tell me "injectors" is my problem. IT'S NOT. My injectors are nearly new. Thank you so much. You probably just saved me a pure mint on repair. Best of luck.

@@giles-df9yu totally agreed....changing the HPFP on the DD series is expensive and not always so easy to get to,inframe with the Cab on....especially on a Freightliner...60 series are the way to go
Thank you brotha! Awesome video, I completely understand this system now. It’s always been a pain because I didn’t really know what’s going on. I have a 13 DD13 in my shop now with a hard start and I new there was a check valve in that thing just didn’t know where. Thanks again man! Wrench on! 🔧💪🏽🤘🏽
Man I like your UA-cam videos. They really help me save money. I have a 2015 Cascadia. My fuel water separator is draining out overnight and I already changed the check valve in it. It could be draining out faster than that. I have to put fuel in the separator in order to start the truck every morning. I see a lot of bubbles in the glass. What is going on?
Thank you Francisco for this video. You did an excellent job on breaking down the components as well as describing and explaining what each part does. I have an issue with my 2014 Cascadia. The 2 main fuel lines on the driver side keep breaking on me. I’ve had to replaced both lines 3 separate times now in the past 2 months. The truck has a starting issue as well, I have Step on the gas pedal to help it start. Could you give me your thoughts on how I should go about this issue? I do most of my work on my car and on my truck because then I know it will be done right. Thank you sir.
Hola Francisco. Like your videos. Learn a lot from you guys. I'm buying my first truck 2015 freightliner. Would be nice to see a video of how to keep a good maintenance on the truck. Like oil changes filters. Maintenance. You name it. Maybe you can make one up or if you have one oready. Thanks. God bless
Thanks for all good information. Have DD 15 trouble starting Put cut off valve on return fuel line . Pressure rise the system with fuel. It started fast...opened valve on return fuel line ...let it run 1 hrs. Closed valve shut off ...next morning tried to crank with Pressure to the system... no luck . Do you think I should go inside to check the internal check valves. I do need to check the ball in the 1st filter your help will be appreciated thanks Frank
Once I brought the OME softwere and started working on my own truck, that is when I started to understand why many mechanics just change the whole assembly.
2015 dd15 rebuilt 2.5 years ago oil is going to my water separator and I’m losing 1.5 gallons of oil at 800 miles no major oil leaks what is the problem please let me know
Wish u could have done this video early.... My was hard to start I try to look for check valve but couldn't find it look on line but no help so had to buy a new fuel housing. But thanks this will b good for future reference..
Francisco excelente buddy good job, awesome job need help I have one dd16 that starts if I prime the system but dies if I accelerate no check engine light no codes, fuel filter runs out of fuel help buddy
Got a 2016 freightliner with a DD15 it cranks but won't start Davco leaks down lots of bubbles, I removed the final filter on the fuel module and filled the housing up and the fuel leaks down in the housing is it supposed to leak or stay up
Man nice video, I been doing my pm on my truck for very long time today I I did pm ,and my truck still won't start I did used 10 gallon of fuel and did primping, any advice on what I'm missing out
I bought the priming pump If i prime fuel filters after i did change and the water separetor do i need feel the water separetor or the priming takes care of it? Thank u
I came across your video and my truck didn't want to crank. Long story short there was metal in my fuel tank system and do you think do I need the whole fuel pump etc??
Hi Francisco my truck sucking air through the fuel filter housing t(he mechanic said) where do you think? They told me I have to change it the filter housing do you think is right?
I can't find the second check valve. I'm losing my mind! I cannot get the truck to prime at all. It would start before with hand prime now after a few months it won't prime. Any suggestions?
My tanks are holding fuel at the top of the tanks , so my gauge is showing full but I k ow it’s less then a quarter tank fuel . Do you know what is the cause of the problem
I have DD15 cascadia there is a problem with the fuel system. If i need to start the engine i have to add fuel to the water separator and pump it . And the next day the same problem please advice me what i have to do. Thank you
Hey Francisco my prime pump doesn’t work every time I do a fuel filter change I have to put the sprayer with diesel for the truck to build pressure do you think if I just switch the Little Pump it will work
I'm having trouble starting my dd 15. It won't pressurize fuel. I used the tool and it just emptys the tank for the fill tool. I put 3 tanks in. I don't know what to do
Francisco pregunta porque eatoe fuller tranmicion modular tira aire en los cambios de avajo. Le puse una nueva y siguio licando. Cuando le puse la nueva y le puse en primera la tranmiccion estava en alta yo la tenia low
Mr Francisco tengo un cascadia dd15 q necesito cada mañana pompearle para q suba el diesel y encienda, a puedo hacer al respecto un consejo x favor, gracias.
Okay I have a 3 filter system. I just changed the Fuel quantity valve to fix surging while idling. It fixed that problem now I have to crank it with starter fluid and It just showed a code for low DPF Fuel pressure. Spn3480/1 after 2 days of driving. I wonder if one of those check valves will fix my problem.
Hello Francisco I have 2011 Freightliner Canscadia I that won’t hold prime after sitting for 6-8 hrs I prime it fires right up but I got the old 3 filter system any advice of what might be the problem?
Freightliner hasn't made parts for the three filter systems in two or three years. As he said it cheaper and better to convert the old 3 filter to the 2 filter systems. But it really better to not have a dd 15
some housings are different and are not equipped with check valve. anyway, detroit is forcing buyers to buy the whole fuel filter housing instead repairing it by not offering replacement parts.
What year is the engine of this particular module? Im having a crank/no start on a 2011 dd13...weird crank issues..starter will only engage for 3 to 5 seconds...scanner is showing good rail pressure and mirrors the desired (I think it was 340bar)...truck attempting to start but wont actually run...checked all fuses,clean power,showing over 150rpms while cranking...another technician replaced MCM module due to water and oil damage(module was full of liquid), but engine still will not start..I do see some smoke coming from the stack during the short cranking, but still wont start under its own power..in start position, engine will only crank for about 5 seconds,then stops rotating...engine does start on a shot of start fluid(which I dont like using)...but shuts down as soon as I stop spraying.....checked all 6 modules on my scanner and not getting any codes..am able to see all of my live data now too...prior to MCM replacement was not getting communication, but now communicating after replacement of module....also,did have a code for MCM not shutting down-battery floating, but all terminals are clean and batteries are good......this is in a 2011 Freightliner Cascadia....engine was deleted, but not sure if new module is affecting the deleted DPF.....engine is attempting to start,but is acting like a fuel issue....also already checked all fuel supply, filters,etc....any other recommendations would be very helpful..im use to the 60 series and not very familiar with the DD 13....wondering if the prior delete with the new MCM is the cause of this...thanks in advance 👍
I have dd15 and when it’s on the road it starts losing power and then it shuts down. When I hit the feet pump 20-30 times then it starts working. Its showing spn94 dlvrpress code and spn3509 snsr volt code. What should I do?
Sir, the tip of the straight bracket, in the large compartment, cracked open. Trying to remove the fuel filter. But you say; that it doesn't have more than just a simple function. And is just to positioned the fuel filter, right❓ Please respond😊
Hey could u pls do a video on three filter system . Am having hard start no fault codes but hard start if I park for 10 mins plus . If I switch of and start immediately no problem. Is there any valve on return or in the system which Keeps back pressure.

I appreciate your video Mr. Amaya. Thanks!
Hi there
I watched your video very informative!
please provide information on spare part numbers such as Filter Check Ball and bolt
Brutal su video viejo!!!
Francisco, great video. But did u happen to make one for the 3 filter system? There are differences that seem significant. Thank you sir!
