The gas gauge on my 70 Impala is stuck on 1/4 tank. I disconnected the wire leading from the tank to the gauge and grounded it to the bumper. The gauge went to mt. When i reconnect the wire it goes back to 1/4 tank. I think this is telling me the sending unit is stuck. Am I correct? I just want to be sure before I drop the tank. Thanks for your help.

Either that or you do have a quarter tank of fuel.

I had the same experiance when we bought our 68 Impala that had set in a garage for several years before it was hauled home and everything was serviced, brakes, transmission modulator valve and a new tranny filter change of coolant, oil and ATF, differential and a new set of Goodyear tires, while I was doing the "get ready to drive" I bought a nos fuel gauge & sending unit and a dash unit on eBay. but once I started driving the car and added a couple tankfuls of Premium and a pint of MMO at each fill, LO and Behold! the original gas gauge started working!...Now I have a spare set.The only problem was several months later,when I started using the A/C on a tour trip the fan clutch tried to kick in on a hot day, froze up and knocked out the fan clutch and the water pump bearings. One of our club members that was trailering his 60 2 door HT unloaded his car and we loaded the 68 on his trailer to take to the tour hotel, I got parts at a local NAPA store( overnight delivery)and with the 68 still on the trailer, several club members and I replaced the bad parts, when it was fixed We offloaded it from the borrowed trailer and drove it 400 miles back home.

A new sending unit took care of the problem. I'm ready to travel.

Aren't happy endings cool?!?!?

Travel well.....
