Gas leaking from tank overflow tube

My 81 1100E started leaking gas on the floor of my garage and I traced it back to the fuel gauge overflow tube coming out of the tank. I'm wondering where to start looking the gauge it's self, the petcock or carbs? The gauge works but I just ran some seafoam through it possibly dislodged something. Just wondering where to start any help would be appreciated.

Drain the fuel tank (set petcock to prime after running hose between petcock and gas can).

Remove the fuel tank.

Remove the sending unit assembly and inspect all the parts.

I recommend a new sending unit seal at minimum but you need to inspect the parts before rushing to the solution.
 
the gasket has gone on the fuel level sender. you may get away with tightening it up but i would strip it out and fit a new gasket
 
Thanks, should be an easy fix. I have a parts bike if anything else is bad.
Anyone know if it's a rubber gasket or if I can get away with making one out of some of that hardware store gasket material?

Hi Mr. jay66,

I don't think I have properly welcomed you yet. But first, have a look at the "Tank Cleaning with EvapoRust" guide or the "Fuel Gauge Send Unit Repair" guide on my website. They'll have pictures of the area you're dealing with if you'd like to have a look at the send unit in the tank.

Now let me dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

I covered the gasket area on my sending unit where the wire goes through with JB weld on both sides. Haven't had a drop leak in almost 4 years. It's an every day rider, so I keep the tank full just about all the time. A new replaceable main gasket wouldn't be a bad idea either, It can leak at both places and drain out the catch tube.
