Hello, looking for some guidance. I have a 07 c6 base. I have the dreaded gas smell and my fuel gauge constantly many times a day goes from empty to the amount of gas then back to empty.
So I know the fuel level sensor needs to be replaced. I've read that on here that everyone just uses the z06 fuel pump. I looked at the DIY and its a bit too much
for myself. I've done plenty to the car myself but Id rather just pay a shop to do this one.

My questions are:
1. Is the z06 fuel pump plug and play? Want to make sure if I take it to a shop that doesn't normally do vettes that everything will just work without re programming.
2. Is there a fuel level sensor in each tank( I imagine there is, might as well replace both of them if that's the case).
3. Which z06 fuel pump would I use or how can i find out which one is the right one? When I look at chevysparts there is a fuel pump and electric fuel pump. I just want to make sure I get the right parts.

 

Never read where Z06 pump is desirable over the 6.0 pump so can't answer that one. The new pumps should be improved to prevent the cracks at the hose connection on top.

The tanks each have a pump (left is electric, right is venturi) with a fuel level module/sensor attached. You can get the pump, the sender or both as a unit.

In 2007, GM changed the design of the fuel sender, reversing the resistance readings as the level goes from full to empty. Be very careful that you get the right parts.

EDIT: I see where you are going to have a shop do the work. Generally they supply the parts so the job will be warrantied. As you probably know, most won't warranty the labor if you provide the parts and they happen to be wrong or fail. And that labor aint cheap on this repair.

 

Why would you take it to a shop that doesn't normally work on corvettes for this repair, seems like you're just asking for trouble? I do know what you mean by this being too much to handle yourself though.

 

My fuel pump quit on me end of July. Had the car towed to a dealer and the car sat for eight months due to a parts shortage. Finally called GM directly and was able to get a part a short while after. I say this only as a heads up that you could potentially be without the vehicle for a while - we do live in strange times after all.

They only replaced the driver side pump in mine, which in hindsight I am beyond grateful for as they were able to complete the job without removing the drivetrain, just the exhaust and the rear wheel/tire (as far as I know at least, there could have been other parts removed of course but the transmission was not one of them). If they had dropped the drivetrain I would have done the right side fuel parts at the same time.

I recommend taking it to a good, reputable shop if you can. I did not go to the local Corvette shop this time but ended up taking the car there afterwards as they pinched the NPP vacuum line when they reinstalled the fuel tank (mild to wild stopped working as a result). Any money I potentially saved will now go towards fixing that. I realize I could also demand the NPP be fixed by the offending party, but to be honest I don't feel comfortable with having them try to fix it at this point and would rather pay to have it done right.

That's not to scare you completely - I've had good success outside the Corvette specialty place for other service needs. But for a job like this their expertise and fee is worth it as far as I'm concerned.

 

Aslong as theres no vette specific programming to do. I don't see the point of going to the dealer or the shops that know the vette and paying the premium. They are significantly more expensive.

 

Great advice. Ill check and make sure all the parts are available. My car actually has been working fine for 6 months. Check engine light is on saying service fuel system. But thats cuz fuel level sensor is going crazy.

 

Did you read the part in Mike3LT's reply where they pinched his vacuum line to the NPP?

 

Once one tank is removed i would change out the other fuel pump since removal only takes minutes. The factory left over shrapnel in the jet pump plugging the venturi eventually. Buy a new sender as well. The driver pump should come with a new sender. Ditto on 2007 being the year the sender resitance tree got flipped. https://www.corvetteforum.com/forums...backwards.html

 

Well... looks like im going to the vette shop. Walked in ready to drop $$$ for fuel pump, walked out deciding might as well just do it all lol.
So my car has 80k miles. He was like if the rear is already down, ill just charge you half the normal labor to change out the clutch. I think he is
going to use the z06 clutch. Since I got 80k miles, seems like I might as well do it. Then since that will be down, I have z06 headers/manifolds sitting in my garage, so I asked
him to do that too lol.

Just going to get the z06 pump installed and he is going to change out everything. Not sure if the z06's experience the gas smell, but atleast
ill be good for another 10-15 years.

 

Nothing wrong with what ur doing. If u have the money and a competent shop doing the work ur good to go.

 

I had it done earlier this year by an independent shop. ~ $2500. They did need to drop the rear end to reinstall. I would not recommend doing this yourself.

 

I just had my 38K mile 2007 C6 fuel pump fixed this week. I took it to my local dealer. They had to order the part but only took 1 day to get it. The Tech didn't drop the rear end or anything else that I could see. He just removed the rear drivers tire and dropped the tank. He did say the new pump was reinforced and shouldn't have the leaking problem. My friend is the service mgr there so he had one of his Techs fix it after hours. I just had to pay for the part and I gave his Tech a good tip.

 

Your repair shop owner is correct in saying that "while we are torn apart, let's do the clutch also"....now would also be a good time add a remote clutch bleed line to make it way easier to change the clutch fluid

 

Had mine done they didn't have to remove trans $2100.00
