'88 F-150 Fuel pump questions and clarification
1988 F-150 4x4
5.8L, 5speed manual
133" WB = Reg cab and 8' box
dual tanks. Front tank = 19 gallons and rear tank 12-13 gallons.
The problem.
The front tank was replaced 4 years ago with a new steel tank. My money was short then so I had them re-install the old fuel pump assembly. 2 years ago I started having starvation issues from the front tank but no issues with the rear tank.
I took the truck back to my favorite mech. and he performed all the tests and he determined that the pump was shot. He replaced the pump with a Carter pump from CARQUEST. The pump lasted about a month and the failure re-occured. He put in another carter pump from CARQUEST. Same symptoms the same day. He then replaced the electrical connector to the pump. The truck ran great for just over a year and now the failure has re-occured. I can no longer hear the pump running and the truck dies just moments after switching over from the rear tank.
Today, I called Auto Zone for pump info. The sell the AIRTECH pump for $110.00 and have 12/12000 warranty.
Carquest and NAPA both carry BOSCH and CARTER pumps for about $150.00. Again 12/12000 warranty.
Ford sells the MOTORCRAFT pump for $206.00 and it carries a 12/12000 warranty. Ford will not disclose the actual manufacturer of the pump.
These Carter pumps have not impressed me.
Is the Motorcraft pump at 25% higher in cost really any better than Bosch or Carter, two top names in auto parts?
I'm a bit of a dummy here on this one and really need some assistance.
Sorry for the long post.

The pump that Ford put in there at the factory lasted from 1988 until 2005. That's 17 years, and the replacements have lasted a month and a year, respectively, and you aren't sure if the money for a Ford pump is worth it?
Not to say that you don't have some other problems going on, like a bad ground or faulty wiring somewhere that's contributing to the failure, but the money is definitely worth it.

I hear what your saying but isn't the MC pump a rebuild or are all pumps new?

Aside from the fact that the OE pump lasted 17 years, I need to know why the MC is 25% better than the rest before I buy anything.
One thing to note. The parts guy at Ford was the only one of the four that I called that asked the wheel base of the truck as the alternative pump to mine fits a 17 gallon tank which was installed on different wheel base trucks.

while you have the relay off, look inside the plug, they get green corrosion in there, usualy a dose of wd40, and a little scrubbing cleans it up. that could be a problem too

The fuel pump relay is in good shape no corrosion.
The electrical connectors to the pump were replaced last year.
I will however take all of this great advise and act on it and give everything a good double check.
The pump runs long enough to get me a couple of miles down the road and then she starts to die. I have to switch tanks to get her right again.

does it do this with a full tank? usually if it only does it after the tank reaches 1/4, the pump is bad. the weight of the gas bypasses the pump until that point. if does it all the time, I would siphon the gas out, and see if it has water in it. usually when an electric pump goes bad, it quits, and don't come back to life.

Hang on a second.
This is an 88, right? So you have the two in-tank low pressure pumps, and one external high pressure pump. There is no way that an internal low-pressure tank pump should cost you that much. It sounds to me like you get getting the price for either the external pump or the high-pressure internal pump.
