I'm going to replace the OEM fuel tank with a Titan 60 gallon tank. During this process should I replace the lift pump as well?
The lift pump is working fine, but truck has 175,000 miles on it...not sure how long the fuel pumps last and I'd rather do it while the tank is off the truck rather than having to replace it in the future. If the pumps tend to outlast the truck, then no need. And, no need for higher volume pump, just wondering if I should replace the OEM pump.
If you feel you should replace it that is the best time to do it if you already have it out. Keep the original and have it tested if you do replace it, if OK then you have a spare on hand!
$220 dollar working wear item that if it fails can destroy your $1200 dollar or so CP3, that has 175,000 miles on it ? and you already have to remove it anyways ?
bad lift pump will not destroy a CP3, the Duramax uses a CP3 also and they have no lift pump. The truck may not run without the lift pump but that's about it.
Okay, I agree....silly question. Just wasn't sure if these things fail often...sometimes you put a new part on and it fails immediately and then you ask yourself...why didn't I just leave it alone! If it aint broke don't fix it...
well thats good to know, figured starved for fuel, super high pressure, equals more heat, and no lube. Soooo.
