I am in need of a new sending unit and I was told I need to check to see if I need an FPH sending unit and to check the wiring harness for a print of FPH on the sending unit? Am I checking the right spot? What is it and if I dont have it what does it mean?

????

The letters will be on a yellow piece of paper taped to the harness that comes off the connector comming from sender/pump. The only thing I can think of is that the letters designate particular lengths of harness... as bizzare as that sounds.My sending unit is out on my z, and have yet to replace it. I keep hearing over and over that any sender will work, but you have to cut and spice wires. I finally bought one(sender) off of a member here and am hoping that I can get it in soon. MY letters are FPC, my connectors are black and the sender I bought are yellow.


Cheers!!!

A picture is worth a thousand words !!!!!

The first pic is from an 1983 Carb: "FAA"

The second pic is from an 1986 MPFI: "FEM"


All of the Carb Pick-up connectors I've seen are black and have 2 wires - just for the fuel guage. Most of the MPFI, TBI and TPI connectors I've seen are yellow - but I've seen Orange as well. Those are 3 wire plugs, The additional wire is for the Fuel Pump.

Thank you for the pics, that is helpful. However, my crossfire car I was talking about had a 3 prong and it's black. I wonder if it's set up by year?

any updates on your progress?
