I am wondering if anyone has experienced the same issue as I have.
I have a 1991 Extended Cab 4.0 Ranger.
in 2019 I decided to change the fuel pump because I had the bed off. The stock one was working perfectly fine. I used a carter pump for an extended cab truck. Of course I chucked the stock pump so I can't really check it. I immediately noticed that my range had been shortened from about 300 miles per tank to 250. I also noticed that it would run out of gas when the guage said 1/4 tank was left.
So I figured out that the regular cab pumps were like 1/2" deeper than the extended cab pumps. So I purchased a new Delphi regular cab pump. It fit, although a little tight. It also didn't read on my gauge correctly, but I was able to bend the arm until it read correctly.
Well, it went about 4 years and died. I would notice cutting out on hills, and especially when it was hot out and I was low on fuel. So I put in a Carter for a regular cab. It lasted 1 road trip and started acting up.
So I decided a motrocraft would be a good idea. I ordered a Motorcraft PFS-37 on eBay. $400. New Old Stock. It was for an extended cab. I got it home and it was 1/2" shorter than the replacement. So I ordered a PFS-38- a regular cab pump. It was longer, but this time I drained the tank and guess what? It was bottoming out in the tank. Like tight to the bottom of the tank and that is where the pickup is.
SO I decided to put in the PFS-37. Today it ran out of gas. According to the gauge, I still said I had 1/4 to 3/8 of a tank left. Only took 15.7 gallons. It used to take 20 gallons.
Has anyone else had this issue? I really wish I had the original pump! It wasn't even giving me problems when I replaced it!
