Bad Fuel Pump/Sender Replacement Advice?
2006 C6 LS2 A6
My car is having the infamous bad fuel sending unit wonky gas gauge issue. I just dealt with it for a little while, but now it's also having the fuel pump crack/leak gas smell issue. Not a big deal. It's a 13 year old pump at this point, but I need some help on what to replace it with.
Since I've got to drop the dang tanks, I'm saving myself from having to do it again in the future and want to change everything out while I'm down there. So the both fuel pumps and both fuel sending units.
Here's what I need help with:
From what I could find, I can just replace my fuel pumps with the Z06 fuel pumps/senders. They're listed as being the same. So I don't think I'll have an issue using them. Anybody have any objections to using these?
I was looking at these units since they both include the sensor/sending unit:
Racetronix TU476-1 (Left w/Sender)
ACDelco Mu1889 (Left w/Sender)
ACDelco MU1892 (Right w/Sender)
Why Z06? well I'm highly considering installing an A&A supercharger kit in the future. I may not, but it's definitely on the table. I know you need to use a Boost-a-Pump (BAP) with the standard fuel pump, I was wondering if you still need use a BAP if you have the Z06 pumps or that Racetronix pump installed. I have nothing against the using a BAP, but if I'm replacing the pump anyway I might as well save future me some trouble.
Secondly, anybody see any issue with using these pumps if I don't end up installing the A&A? I don't see how they would hurt anything other than being overkill for my DD driving around. As long as it's not hurting anything I really don't care, but if anyone knows otherwise I'd appreciate the heads up! Thank you!
