I was extremely nervous to alter the fuel sending unit during this install but this video made everything simple and easy. I utilized both the instructions and this video side by side and the video was much simpler and easy to follow. Great video and great product. I immediately noticed the results in my truck. Would totally recommend this product and video.
why do some lif tpumps require you to drop the tank and alter the sending unit but others dont? Whats the advantage? Looking at buying a '15 lml and want to add a lift pump to protect the CP4 but I dont understand why this video has them altering the sending unit but other videos and instructions Ive found do not.
@@andrewjordan9183 The videos that you are referring to are 11-15 LML. The 15.5-16 LML is the same body style, with slight differences mechanically. The fuel sending unit in 15.5+ are more restrictive and require drilling. If you're unsure which LML you have, you can look at the exhaust where it is bolted to the downpipe right behind the passenger front tire, behind the frame. If the exhaust is held onto the downpipe with a clamp, it is 11-15. If it is held on with three bolts, it is a 15.5-16.
You should do a giveaway for the basic fuel system! Just bought my first Duramax. 2016 LML. So def thinking of doing a FASS system because of the CP4 unit... great video!!
That's awesome man, congratulations on getting the Duramax! If you have any questions about the system you are more than welcome to reach out to us anytime!
if you still got that duramax stop driving it immediately and ditch that junk cp4 with a cp3 conversion before you have to spend 10k in a whole fuel system
Damnnn and here i had it backwards Now based off the diagram on the back of the filter and this video i noticed i been running for over a year now with my system improperly! Alot of people are under the impression that the low tube is for the Fuel filter rather the Water seperator so ive had mine swapped and ive had a shit ton of issues not realizing thats the issue! My new filters arrived today and i was looking at the diagram i didnt realize that with the Black base units on the LMLs the low tube is in fact meant for the water seperators! it might explain the intermittent Hesitation ive been having because the filters were not in the right locations! The water seperator was on the suction side!
November 5th 2023 just installed my signature. Lift. Pump works good, the only problem is my check engine light. Have anything to do with? Because I bypass the factory pump.
Hey there thank you for reaching out and we apologize for the trouble you're having. Whenever it's convenient please reach out to our service team at 636-433-5410. We'll be happy to help!
Hey Chris, we do greatly apologize for that sir! Whenever it's convenient please give our service team a call at 636-433-5410. We will be happy to help!
Great question! Yes, this system is designed to integrate with the OEM in-tank module, and that installation method does require some simple modification. However, you can also opt for a sump kit, which will bypass the in-tank module altogether. We definitely recommend utilizing the OEM pick-up module whenever possible to ensure maximum fuel range, but a sump is a solid option for the simplest install.
I ordered the stk1002. It’s incorrect. Do I need the stk1005 for 2015.5 duramax? Also the pdf instructions for stk1005 has a different 5/8 tube than what’s in this video. Looks like the one in the stk1002 kit
Hey Douglas, thank you for reaching out! We'd be happy to get you the correct parts. Just to verify what you have and what you'll need typically we ask to give our service team a call at 636-433-5410. They will be able to assist with this and get you the correct numbers to place an order over the phone.
Great question, and to get you the best help here please reach out to our service team at 636-433-5410. They will be able to help walk you though how to set this up!
That's a great question! The amounts used are very, very minimal and virtually none ends up in the actual fuel line. If some were to get into the actual system, it would either be filtered or burned off without any issues.
So it looks like you are returning fuel through the old suction line. Is that correct? I've been thinking of adding a sump but don't like it hanging from the bottom of the tank this looks much better
Look to see it your truck has the fuel tank skid plate. I went with the new Beans sump and the sump is hidden under the plate. It is also a lot easier to install the sump. Just make sure that the truck is almost empty and then jack the rear end up as high as you can get it so the fuel go forward some. I drill right where the flat spot is and some fuel came out which is great because it washed out the plastic shavings from drilling. Did it over a year ago and no problems.
We are returning fuel to the factory suction line on the 15-16 Duramax. This helps keep the basket in the sending unit full of fuel at low tank levels.
Awesome question, and this is our R&D department area. We do apologize as we wouldn't be able to do installations there. If you don't mind me asking though were you looking for a shop to have a system put in your truck? If so we have a large dealer network, and can help you find one close to you. Our service team number is 636-433-5410 and they will be happy to help!

I got a question I think I did something wrong I installed the pump its been like 6months now ,so I was replacing the filters and with new filters I left them a little loose and turn the ignition on so they would fill but after like 3min they never filled so I was curious if the truck would start and it did and ran fine for like 10min did I do something wrong that fuel is not getting to pump ??? Or is it normal for it to still run with out the fass ,I also installed a sump in my tank???

The 15-16 Duramax sending unit is more restrictive than the 01-14 Duramax sending unit so you do need to modify the sending unit with the parts included in the TS C12 kit.

@@colbymonroe6131 You bet! Give us a shout if anything else comes up.
Does a “no drop” sump kit bowl only bypass the process of modifying the fuels tank module??
Correct, you just would not have to drop the tank to install the suction tube into the sending unit.
How many billable hours should we expect for the install?
Great question! If installed according to our instructions, roughly 6 hours can be expected.
Dumb question but isn’t putting grease on to any fuel component going to contaminate it?
That's a great question! The amounts used are very, very minimal and virtually none ends up in the actual fuel line. If some were to get into the actual system, it would either be filtered or burned off without any issues.

Yikes, on older models you didn't have to remove the gas tank... What does the gas tank modification do?
The 15-16 Duramax sending unit is more restrictive than the 01-14 Duramax. Modifying the factory sending unit will eliminate that restriction.
