Fuel Sender Diagnosis

[The Car Whisperer]

I just started driving my 86' after the long winter storage. Just before I put it away last November it had a full tank of gas and I added Sta-Bil. I started it a few times during the winter and kept the battery charged up. I just recently filled the tank up again after storage, the fuel gage read 1/2 tank, but when I filled it up it took almost 14 gallons! Is it possible that the float is stuck or maybe the sender needs to be replaced. This is an axpensive item so I'm looking for a way to verify the function of the fuel level sender.

Dump a 20 gallon size bottle of Chevron Techron Plus in it,Good chance it will fix you right up in a day or two!

So you think it could just be stuck? I'll try the Techron and let you know what happens.

Probably just sulfer build up on the sending unit, which 20 oz of Techron Super Concentrate should fix, try two full tank (full to empty) fulls if one doesn't do it.

I'll second that!!
