ChrisMinelli Posted January 2, 2021 Report Share Posted January 2, 2021 I’m working on getting all the instruments in my 52 Plymouth to work and after replacing and fiddling with the tank sending unit I grounded it with a jumper wire and the fuel gauge worked like a charm. The manual seems to think the retaining ring itself is enough of a ground for the unit. I’ve cleaned and tightened it and I think the tank itself is no longer grounded. (It’s on my list to replace but until then I’d like a working fuel gauge). Is there a place I could run a ground wire to in the trunk? My initial thought is that I could just ground it to the trunk but I don’t think drilling above the gas tank is a great idea. Could I run it through the taillight hole and ground it to the frame? Anyone solved this problem before? Thanks. Quote Link to comment Share on other sites More sharing options...
dpollo Posted January 2, 2021 Report Share Posted January 2, 2021 Slide under and run a ground lead from the frame to the steel gas line. Quote Link to comment Share on other sites More sharing options...

Later model Mopars had a factory jumper that grounded the tank so this should work. 1 Quote Link to comment Share on other sites More sharing options...
JBNeal Posted January 2, 2021 Report Share Posted January 2, 2021 What is your path to ground? The shortest path is the best, through the fewest number of mechanical fasteners...for optimum performance, the battery grounded to a starter mounting stud improves cranking speed, and from there a ground strap can be used over to the nearest frame rail to turn it into a buss bar where the sending unit can be grounded ?
