I’ve had trouble with Airtex on another application but this may very well be a good solution for those whose hanger and fuel level sender is still in good condition. At least it gives an option. How long has yours been installed? (I had an after market pump (not Airtex) fail on the first trip at about 250 miles. I realize OEM can also fail.)

According to the information given us here on the forum, it does not appear to be a proper pump for the application. No. It may "work" to some degree though.
The pump assembly or "hanger" is what's giving some fits. Once one of those has been found that works acceptably then you could always swap whatever pump is in it for a more suitable Walbro pump. Like maybe this one-

We used two ratcheting straps one at the front and one at the back to lift the tank off the ground and suspended in place to reattach that pipe. After that is was as simple as ratcheting the tank all the way back up and bolting it back together.

So did this work?

It doesn't work. She isn't holding pressure the way she needs to because the pump is significantly less psi. I'm waiting on the inline pump to arrive. Installing that with the pump already on the tank should work fine. Will update again when I can.

the pump is back on the market Motorcraft-PFS48 Fuel Sender buy it now!!

[1997_pace]

I just purchased my own on amazon

[MarvinG]

That is really good news. I’ve put over 1500 trouble-free miles on the PFS48 I purchased a few months ago.

[1997_pace]

So it is working well then correct?

[MarvinG]

Yes it is the OEM unit and works well. I’ve read where some had problems but that happens with all products. I’m 100% pleased with mine. (And I’m a perfectionist when it comes to this kind of thing. I don’t want trouble, I want to be able to drive it and forget it is back there.)

Do you know by any chance how to wire it up..

[GypsyR]

If it's a "three wire" it's not hard to sort out. One wire is just ground, another a variable ground that is the fuel gauge sender, and the last is powered up when you turn the key on to run the fuel pump. Colors I don't recall, but "Subford" has been kind enough to post a few copies of the factory wiring diagrams in various places on this forum.

[MarvinG]

It will come with a wiring diagram, at least mine did. And if not, it really isn’t hard to sort out. Subford’s info is available, and we can help you if need be. If yours is three wires, you will hook the ground to the two grounds and one wire goes to the pump and one to the fuel level sender. I think it will be largely obvious to you when you get into it but as GypsyR pointed out you can find out which is the + pump wire by measuring with power on from the ignition switch. Do be careful, you are working around open gasoline and with fumes coming out. I kept a fire extinguisher at hand at all times and was careful not to do anything that might cause a spark. You would do well to sort it out before you take the pump out of the tank so you don’t have the fire hazard while messing with the wiring. You will likely have to butt splice a wire or two. The splices are outside the tank and you can use form-a-gasket to waterproof the splices if you want to. In my case, someone had already adapted the three wire to four wire. I just ran a new ground to the frame and spliced it into the ground wires to get my voltage up where it should be.

In the picture the new pump has 4 wires. Red, red/black, black, yellow
