Hi John, (and everybody that posted a reply to my questions) Thanks for taking the time to explain things. The sender seems to work fine (I ohmed it, as well as tested it out of the tank, hooked up to the gauge, and all positions on the sender correlated with the gauge, so I guess that part is OK. Looks like somebody changed the cork and put a brass float on the unit. It had a rubber (I think, it was in such a bad shape that it totally disintegrated) gasket between the float/pickup tube flange and the ring that locks it in place. Is rubber the correct material to use, or should I go with cork gasket? And, I think that the gasket should be between the tank and the float flange, right? Not the way they had it…. I will go look at the tank and see if the o ring seal for the filler neck is there and what kind of shape it is in. Probably will replace that, no matter what condition it is. I have a lot of 30s (and other) cars, so I know about the ground importance for the sending unit. I guess it applies to any car, but I always solder a short jumper between the sender and hook that up to a clean ground screw on the frame. Again, appreciate your input, Best regards Tom On Jan 6, 2018, at 7:01 AM, John Grady <jkg@xxxxxxxxxxxxxxxxx> wrote: Hi Tom There is an o ring where the filler pipe slides into the tank ;in a groove in the tank . usually in pretty good shape , but can get new one. Judgement call . Do not use o ring from cheap kit in red o ring box. ( China) Must be gas resistant . .. Possibly grease the pipe after thorough cleaning ( front end grease ). How is the cork ? I recently replaced the cork with Ford style little brass tank gas float by using # 12 building wire solid, and solder , cut off arm wrap loop around brass tank groove. Clean arm end till shiny wrap wire around it and solder . I also soldered quickly to little tank . Cork can sink . Has to move in same arc thought center of float . Check sender with ohm meter , not the same ohms as common later (60 up) thermal gauges.( 10-90) Mine was 20 to 200 ohms . It was ok , but corroded connection . I also solder a ground wire to the gas exit pipe where it leaves flange and ground that to car sheet metal . Common problem with fuel gauge is poor connections here .
