Default Looking for pics/info of fuel sending units (92-96)

After removing the fuel tank in the 90 and inspecting the fuel sender rheostat it became clear that I can't install it on the 97 sending unit to cure the fuel gauge problem. I don't know if that is because it is a replacement instead of the original though. Does anyone have a sending unit from a 92-96 laying around?

Tomorrow, I'll post a pic of what the 97 rheostat looks like and the way it attaches to the sending unit. It is easily removed and I'm hoping the other years mount in the same way.

Thanks

I realized that the above description was a little vague so I made a special trip to get the sender. I would like someone with a spare sending unit to compare the following pics to what they have in order to determine what years, if any, have this style of rheostat assembly mounting. With this information, I can find one on a junk yard unless what you have is for sale.

this is the rheostat assembly as it appears on the complete sending unit. Take note of the white plastic piece which locks the rheostat onto the steel lines. With this removed, the rheostat simply slides downward and off of it'* mounting perch.





This is the rheostat assembly removed from the sending unit

I need to find one that has an operating range of 0 ohms empty and 90 ohms full. I believe 97 was the first model year that began the 40/250 range but I'm not positive. If you happen to have a multimeter kickin' around too, you'd be my hero if you could measure the range.

Lunch too??

I have a multimeter but I need someone who has a sending unit laying around to confirm both the mounting and operating range.

93-94 don't look like that. There'* no black box inline with the pump wires and the rheostat is white plastic with the metal strip in a straight horizontal line. Pump looks the same...

Thanks, Dame. Maybe I can approach this in another direction by using the complete sender assembly instead of just the rheostat. The lines would need to the same length and diameter and have the correct ends in order to connect to the 97 fuel lines.



The overall length of the londest line is about 16" measuring from the center of the sender in-tank body. The supply line off the sender is 3/8" diameter, the return is 5/16" and the vapor is 5/16". Only the supply and return have the fittings for the quick release nylon fuel lines.

Wow..a great engineering feat was accomplished. He'* got the sender and tape measure balanced on a single bottle of 409? Impressive!
