Lift Pump Symptoms
 

what happens when its going out? my truck started sputtering then it got to where when you put it in drive it idles rough i changed my fuel filter just a few ago and it was half full of fuel shouldnt it be full? how hard or long does it take to change the lift pump? whats to it?

Its going out you need to change it asap you dont ever want to run it long periods of time its not good at all on your pump i would suggest an upgrade to an airdog their the best

i put a post up about our lift pump about a week ago, you should check it out because mine was doing the same as yours. its called truck would not start, figured out the problem.

is it the original pump? how many miles are on it?

no it was changed a while ago a year or two

The only way to know what a fuel pump is doing is with a fuel pressure gauge.

it tricky to swap out lift pumps? any tricks or it straight forward bolt of bolt on

2 bolts, 2 line connections, piece 'o cake.

do you have to prime it or some thing? just pump it then crack injectors or what?

You may or may not have to prime anything. Just change it and crank, see if it fires.
