the fuel gauge on 31 ford leaks around the brass threaded ring slightly whenover 3/4 tank full, I have the spanner tool to tighen it,s not what I would say is real tight, my question is how thigh should it be I don,t want to break any thing, thanks in advance, wayne

You're probably going to be better off by draining the tank and REPLACING the gaskets (use cork), and reassemble. If you're still running a cork float and opportune time to replace it with the new style float. Disconnect the battery BEFORE draining tank. JMO

there is a rebuild kit for the guage . drain the gas down to like 1/2 tank & you can pull the guage , replace gaskets & reinstall .

thank you 1931, in order to remove the gauge and float unit does the tank need to be completely drained? or just below 1/2, and does the unit come out of the front of the tank? thanks again wayne

FYI. There are TWO tools needed to R&R the gas gauge. One to hold the inner ring around the site glass and one to hold the outer ring. It is hard to do a proper job without both tools.

thanks Richard, I do have both tools,wayne

Sometimes the nuts are very tight and you need to press inward very hard while unscrewing the outer nut. Then you'll have the complete unit come out the front, and you can remove the float arm, and slip the unit over the edge of a 3/4" board in a vice. This will give good support to remove the inner nut. I've had to soak the inner nut with Kroil before it would loosen. Use cork gaskets on the fuel gauge.

[3340]

yes I have the cast aluminum ones, thanks

a little filing or sanding on the aluminum tool will help it fit better.

thanks, the spanner (inner) seems to fit rather well, I have not tried the outer one as yet, I as well as all of us are used to making these after market stuff work.wayne
