Curious if there is a way to “bench check” a fuel sending unit? Currently I have my tank dropped for refurb and seems like a good time to make sure it works. Not ripping all that stuff back out so is there a way to check it? I’m guessing if I plug it back in and move the float in theory the gas gauge should move? 305 carb engine…for now

 

Yes of course you can just hook it up to the car and check using the gauge. Works fine. Might have to use a clip lead or some such to ground its flange.
