How to tell if your lift pump is going out.

As I understand it if your lift pump goes out your injection pump will crap out. If you dont have a fuel pressure gauge(I know,I probably should get one) How can you tell if your lift pump is going bad?

Hard to say. Some guys have no problems then it just wont start. Some fry there fuel pump because of low fuel pressure. Genos has some fuel guages for a reasonable price. Fill in your sig so we know what truck your working with. Im guessing 98.5 to 02?

Its deff. better to spend the $150 on a guage than the $1500 on a new Fuel Pump. Better safe than sorry.
