87 22r fuel sending unit

Hi I'm new here n I picked up an 87 4x4 5spd with 251xxx miles a few months ago. When I got it the gas gauge doesn't really work right. When I fill up it says full but when I drive like 60 or so miles the gauge goes to empty. I think it might be the fuel sending unit but I'm not sure. And if it is I found one from a 92 for $50. Will that one work for my truck?

You might try pulling your sending unit out and cleaning the windings with some electrical contact cleaner.

I had the same problem with my 87; dropped the gas tank and found that the winding on the sending unit were worn on bottom half. Mine would register until it got to a half tank then go to nothing.

Don't know about the fit from a 92, I would drop the tank and put the old one then you should be able to see if the other one is the same.

Later,

this is an old string but i'm curious what the name in the chiltons would be for an 87 22r sending unit. sometimes the books are ridiculous in describing things. got the same issue with the gas gauge all over the place. thanks guys.

I don't have a Chilton for my Toyota; however, I believe it is probably shown on the fuel pump if you have a diagram, etc. for that. I have a Toyota 87 Manual if you have a question maybe the answer would be in that. Let me know.

i just inherited an 87 and am trying to go through all the little issues. i've got a chiltons and the owners manual. havn't checked the owners manual yet. frustrating not knowing how much fuel you got except for basic math calculations to get you in the ball park.

How easy was it dropping the tank? would you have rather taken the bed off or was the tank easier?

I don't recall any major problem dropping the tank. I ran it down until the light came on and then parked it and let it run out of gas. I was surprised at how long it took to run out, couple of hours idling.


I have removed the bed before and I think it is easier to drop the tank but either one would work.


Have fun....
