Anyone using a fuel cell that could tell me what fuel sender to use?

April 29, 2010, 10:39:45 AM

I have a 10 gallon fuel cell and without checking the resistance I ordered a fuel level sender that said it was for a mustang, I figured it would work but now when my tank is full my gauge reads empty and when its empty it reads full... Ive seen one with a rang from 0 empty to 90 full but Im not sure that will work ether because the stock sending unit is 13 empty 160 full. Can anyone clear this up for me I dont want to waste more money buying the wrong one again.

Sounds like you have the wrong type sender for your gauge.
For an buttstuffog gauge the resistance goes down as the tank fills.
For a digital gauge the resistance goes up as the tank fills.

From the 87 EVTM:
buttstuffoge gauge, 60-86 ohms empty, 8-12 ohms full.
Digital gauge, 9-12 ohms empty, 154-161 ohms full.

I know its the wrong sender, as Ive been reading about it I guess they changed the senders in 1987. My car is an 87 XR7. I need a sender that reads 13 ohms empty to 160 ohms full and I cant find one. Any 87 up mustang should use the same one so I would think they have them somewhere.

Anyone know if I could buy the 0 ohm empty to 90 ohms full and use a resistor to get the reading right??

just reverse the internal wiring and then calibrate it using a resitor on the top or lower end..

There are no wires, its all sodered to a board but I was thinking about tring something like that...same thing as my oil pressure gauge...I was hopeing I wouldnt have to expirament so much.
