Topic: Bad Fuel Tank Sending Unit

[myyota]

I have an 86 4Runner with a 22RE and the gas gauge sending unit it bad, when it reads 1/2 a tank im out of gas. is the sending unit seperate from the fuel pump ?, how much is a new sending unit and were is a cheap place to buy one ?. would a sending unit from a 91 toyota pick up with a 22RE work in my 4Runner ?.

i thought it uses a float? is it possible the float arm is bent?

[KDXSR5]

It uses a float that is connected to the sending unit, I believe. The sending unit sends the voltage signal indicated by the float.

Yes the pump is removable from the rest of the sender. OEM baby. it just

[KDXSR5]

So if I pull the pump, will the sender come up with it? Then I just remove the sender from the pump? Or does the sender go in a different hole on the tank? I need to replace the sender on the 85, thats why I am asking.

I've got an 85 tank in my 83. diff holes. so was the 83 tank too.

Ok, so I will assume the sender goes in the smaller hole.

The fuel pump & fuel sending units are in 2 different locations on the tank. The access plate under the right rear seat will only get you to the fuel pump. You have to drop the tank to get to the sending unit

Or remove the bed?

He has a 4Runner.

On a truck I would loosen the rear bolts & remove the front bolt & tilt it up.

I was thinking my truck.

Its easy. Buy the part.  Drop the fuel tank out the bottom, i think there is 6 12mm bolts.  I dont remember if the sender is attached(detachable however) to the fuel pump like most are(chevys).  Or you can just make it easy and buy a new fuel pump and sender, but like the dude said previously in the post by stock parts from toyota.
