Gas guage ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

chucks70 · 11-30-2003, 07:41 PM

Can a gas gauge be reset? My needle is stuck in the 3 o'clock position. Can this be fixed? How can I tell if it will work or not? How do you tell if a sending unit is working or not?

Dumb question...Where is the oil pressure sending unit on a 292?

sounds like your not getting power to the sending unit,,,,if you disconect the brown wire from the sending unit of a "known"good unit ,it will do exactly what yours is doing,,,jeff

Mine did the exact same thing. Bought a new one from GMC Paul's and after installing it the problem was gone.

Could be the float is sunk (full of gas) or the sending unit is bad...... or you could be outa gas. Mine is sunk. I took the float out and checked it and it has a few cracks in it. I thought about trying to fix it but decided a new one wasn't going to break my retirement account. The float is about $5 and a new gasket is $1 1/2, throw in shipping and it's about $12.

Slide your seet forward and look at the tank. There should be a small brown wire on the sending unit. If you were to follow that wire, odds are it is broken somewhere. under the door sil plate is a very common place.
It may well be unplugged from the fuse box too.
Shade. It sounds to me like your float is filled/missing. Could also be a bad sending unit, but you could find that out by testing the unit when you pull it out to see if the float is full.
