fuel gauge not working

My fuel gauge is not working, so I am dropping the gas tank and plan to replace it and the sending unit. I need to make a list of things I should order. So far I need:

a) stainless steel tank
b) 3/8 inch sending unit
c) sending unit locking ring seal
d) anti squeak insulator set
e) straps & strap bolt set (maybe?)
f) Gas Tank To Filler Neck Hose, With GM Mark & Clamps (maybe?)
g) fuel tank sending wire harness (maybe?)

What do you think about e, f and g?
Anything else?

Re: fuel gauge not working

I ordered mine from Classic Ind. I also got the SS kit had everything except the, send unit and sending unit wiring harness. I did mine because the tank had a leak that I just couldn't get to stop leaking. Before you ordered the tank kit , I would first make sure it's not a problem in your dash gauge or just a wire thats not grounding ect. before I spent money on tank just because the fuel gauge is not working.

Re: fuel gauge not working

Ken - are you replacing the tank because of the fuel gauge problem or just as an upgrade to an old and/or leaking tank?

Re: fuel gauge not working

I might reconsider. I am swapping out my 10 bolt for a 12 bolt and thought it would be a good time to drop the tank to replace the sending unit and while I'm at it, replace the tank. Now I'm not so sure.

Re: fuel gauge not working

I would suggest first to check continuity of the tan wire from the trunk thru the sending unit to the ground wire on the passeger side strap with an ohmmeter. Ninety ohms is full, forty-five is half full, and so on.

Of course, this is with the tan wire disconnected before the gauge. If you read the resistance listed, then the path is okay. Usually, its the ground wire needing a little TLC, or the brass float now has gasoline inside and does not float any more, hence, empty tank is indicated.

With this said, a resistor of say, 50 ohms, tied to the disconnected tan wire in the body harness and the other end/lead of the resistor grounded, the gauge should read half full/empty.
