6th Gen Camaro LT4 Fuel Pump Install (without dropping the tank)

[@gnquijada]

Invest in a home carpet cleaner with a thin carpet attachment, got it. Gnerally, still the same precuations for any dealings with fuel repair/upgrades.

[@RCCamaro]

Exactly. Or good brushes

[@kebirbro6638]

i have a 2018 camaro ss it shows the codes P069E and P2635 and i run e85 and daily drive it, race it here and there on weekends do u think is due to a bad fuel pump? or a bad fuel pump control module? was your issue similar ?

[@RCCamaro]

I can't remember exactly what the codes where but the one code I was getting was for the hpfp not getting enough psi to deliver and to us we think it had to do with my in tank pump. Since then the code I did get was for a short circuit for the FPCM and we tuned it out. Car has been running great since then and hasn't gone into limp mode. I would say if you're modded and on e85, you could be at the limit of what the in tank pump can do. Unfortunately I cannot look up the SS codes but I would think it's just at its limit of what the pump can provide.

@kebirbro6638 Yo i got the same codes, did you figure out what the problem was ?

I am having same issue 6 months into build.

​@RCCamaro thank you for that update! I am going to do mine this weekend.

[@RCCamaro]

@@thatrealcarguy good luck! It can be a pain in the ass but once you do it you should be good for anything

[@Reapergot2ss]

Did you have to tune the FPCM after putting in the new fuel pump? Because mine won’t start anymore and it’s giving a P069E code

[@RCCamaro]

My car started right away and the only code it threw was a low HPFP code but didn't go into limp mode. I actually drove it around for maybe 2 weeks before tuning the car. I can't find much on that code but I won't be too much help since my car is a V6 so it might be slightly different for your car.

[@RCCamaro]

I would double check that all the hoses were clipped in and that all the plugs are in all the way. Also before starting the car, hold the ignition button until it goes into accessory mode and see if you can hear the pump turn on.

[@nairovirus]

so if i were to go E85 and be doing daily driving and hard driving here and there, you think i could get by without a LT4 pump swap? and did you need a revised tune to be able to drive on it right when you installed?

[@RCCamaro]

Yea if you're not planning to be racing constantly then you should be ok but if you decide to want to push the car more then you will want to swap the fuel pump

[@travisnishimoto7439]

I would not butcher my car like this , remove the tank

[@RCCamaro]

This wasn't supposed to turn out like it did. After looking into the location of where the pump was and honestly guessing where it was made it come out worse. You don't have to do this but for some This is the only option.

[@Manuel_Z_Kayaks]

Remove the tank, IT'S EASY. First Jack the car up. then the exhaust, drive shaft shield, drive shaft... I'd rather butcher under the seat where no one will see it.

[@Manuel_Z_Kayaks]

You were right. . This guy is just guessing as he goes!

[@RCCamaro]

So I couldn't remove the exhaust or driveshaft because I didn't have the time or space to do it. Now as I mentioned in my previous comment, you don't have to do it this way. Is it messy? Yes. Is it easier? Yes but I also daily my car and its my only car so didn't have much of a choice. Now this is covered by my seat I don't have it bare haha. And I admit that I'm guessing, no one has a video of cutting a hole above the pump. But I also make sure I put warnings to keep watching for the actual location.

[@anthonypapa8676]

insted of screw why didnt you heat up the end and squeeze with pliers

[@RCCamaro]

I didn't want to risk damaging the pump as that plastic looks like it may have a high temperature melting point. Plus I wasn't even sure if it was going to work haha. It was a temporary thing until I could find a way to plug it properly.

[@Moemoe-ki4wx]

Is that supposed to get capped

[@nickkrajina]

@@RCCamaro do you need to cap that t section off? I'm at that point and I'm unsure what I need to do with that

[@RCCamaro]

@nickkrajina from my understanding ZL1s have an auxiliary fueling system which I believe that is for (don't quote me haha) but I capped it because I believe you will lose fuel pressure from there. I didn't try it butbi would cap it with something. I used a screw and made sure it was secure before installing.

[@juexskr2492]

@@RCCamaro i wonder if u do loose fuel pressure. I just installed one and getting low fuel pressure

[@Manuel_Z_Kayaks]

OH MY GOOD... DO NOT FOLLOW THIS VIDEO!!! USE IT AS A GUIDE FOR WHAT NOT TO DO

[@RCCamaro]

Yea it's not an amazing video for sure. But this helps at least show where the pump is located. I would always recommend removing the tank and doing the work that way.

[@Parmezon]

What codes was the car throwing? And also when the pump went out did your fuel gauge drop to E randomly too?

[@RCCamaro]

So the code I was getting was a "short to ground" code and we tuned it out. We think it's the fuel management module that thinks the pump is burned out but it just runs better. My gauge never dropped but we saw it was running out of fuel. If the gauge is dropping its your fuel sending unit that's going out

[@Parmezon]

⁠​⁠@@RCCamaroso I just literally got doing the same thing you did. And im still getting the same codes I was before. So you said after you got it retuned everything works well?

[@Parmezon]

And it also the gauge still keeps dropping

[@RCCamaro]

@Parmezon yea the FMM is used to a specific resistance from the fuel pump and will continue to show there is something wrong even though the car is running fine. I could do pulls and after about 4.5-5k rpm the check engine light would come on but it wouldn't go into limp mode or act weird.

[@RCCamaro]

@@Parmezon did you reuse your old float or did the pump come with a new one?
