Fuel Tank Repair

[pow2gran]

I have a 30l fuel tank that leaks around the level sight glass. I have tried gluing it in but the glue breaks down eventually. Any suggestions on how I can seal it up. Unfortunately when I screw it in fully and tighten it up it jumps back up a thread. I was tempted to throw it away and buy a new one. I have a 30l hulk which is essentially the same and there are no leaks.

Any suggestion? Photos attached

have you tried silicone mastic, there are some which are resilient to petrol, maybe worth a try

Thanks Chris I will have a look a silicone I should have thought about that. Happy New Year to you for 2014 - and hope that it comes with good health!

If you struggle to find a silicone to work then you could try instant gasket.

If the tank is polyethylene you might find that some things just won't stick to it, so don't be unduly disappointed if silicones or other adhesives/sealants don't work.
Try a google 'gluing polyethylene' some interesting ideas come up.
