What kills these pumps is air in the fuel.
Where the air comes from is the quick connects on the fuel line from the tank to the pump and, if one insists on running thier tank low all the time, from the mixing chamber in the fuel tank pickup.

I would advise everybody to check their fuel pressure before the run out and buy a new pump.

Then what if you find out you need a pump. Then you wasted like 100$ on a gauge you will prbly never use again.

Point taken.You have to ask yourself now if you want to play it by the seat of your pants, take a guess and make a decision on whether you need a pump or not.
Or just take the plunge and buy one, stick it in and be done with it.
Going on the failure rate of the fuel pumps here on FTE, your chances are pretty good that you'll need a pump. So I guess you could just save the money and go buy a pump.

It's your money. Then what if you find out your pump is good? I got a brand new $300 ford factory pump for $100 from a guy who used that method. For $100 you can install an in the cab fuel pressure gauge and know what your pressure is doing all the time. Or you can get an idea of what your fuel pressure is at the test port with a cheap tire pressure gauge. I like to try to diagnose problems rather than just throwing parts at it.

I got a pump from oh-rye-lees for $100 when I was having fuel delivery problems. Turned out my old one was fine so now it rides in the toolbox as a spare.

That makes sense to me. I used to drive an Ambulance that had to same issue and after the pump was rebuit the power and mileage was back.

Well I just checked mine today for the first time since installing the prepump pump, and I got 16.9 (lieometer says 16.7) so there is the possiblilty that the main pump is getting bad, and the prepump is covering it up or extending the life of the main pump depending on how you want to look at it.
