I think my fuel pump is going out. Last week the truck started losing power at 70. I would give it gas and it would sputter a little and take off. I stopped driving the truck until last night. The truck started having the same problem, only at 60 this time. I am new to fuel injection and figured it was a fuel problem. The truck starts and runs fine under 50. Am I right to assume this? Also, which is the easiest way to change the pump, drop the tank or take off the bed? Thanks for the help.
