Getting 8.5 mpg need help

no need to spray that for a test, we know its leaking bad.

o ring is bad, or a line is snapped / cracked at the pump.

hit the strap bolts with some pb blaster for a day or two before you tackle the job, lowers the odds of that stripped bolt action.

shop is doing this one. my boss caught me doing the tranny fluid change and chewed me out dont need him getting riffed over the gasoline smells lol i will prepare it for them tho lol now lets talk parts ill be ordering from rock auto most likely but need to know the part numbers for the proper fuel pump assembly, the gasket and that metal ring. also the straps. i read somewhere its good to replace those for future maintanence. 2004 chevy tahoe 5.3 V8 T VIN.

id grab a new pump and canister, this way you get a new sending unit as well. re use everything else, shop likely wont have any issues. id not even lube the bolts for em. let them earn that money lol

i find often i can get things cheaper at advanced auto on line with a discount code and have it in hand 30 minutes later. and have a nice local warranty too.

you just need to enter your year make and model and parts that fit will show up in the search. if they show a vin# letter or number make sure yours is a match. the flex fuel pump might be different.

random search for a 04 tahoe, thats pretty much what the whole canister and pump looks like. you can buy just a new pump for like 40 bucks and replace it, but im not sure you can buy a new seal for the top of it.

well look at that, they do sell just the seal. that pumps not cheap, and yours seems to work still. 13 dollar seal might be worth it.

I dunno, the top of that pump looks petty rusty, those lines are probably about to break off, too. I would also buy the lock ring. You gotta beat that thing pretty good to get it off.
