Hey guys, I'm pretty sure after some research that my lift pump is going out. I just bought this truck about two months ago with 180k miles, changed the fuel filter in my regular servicing and found a bunch of metal shavings in the canister. I have also noticed it doesn't hold fuel pressure well, cruising at about 5 or 6 psi but if I accelerate or go uphill it drops as low as 1.5-2 psi. I've heard that upgrading to a larger pump can be really helpful to these engines.
Thanks in advance
