There is always some confusion between builders/plumbers silicone sealer and automotive silicone sealant. You need to get some of the latter I use Loctite 5910 and there are others equally as good, threebond for example.

Blue Hylomar is fuel resistant
There are very few truly fuel resistant sealants, done my time in a shop enviro, flushing blue slime out of carb jets. We use Loctite 5922 paste on fuel senders, which is rated fuel resistant & pretty much an industry standard bodge.
If you'd rather do the job proper like, buy a sheet of 1.5mm nitrile bonded cork, nick your missus nail scissors & cut yourself a simple gasket that's guaranteed to seal & not dissolve into your fuel. Alternatively you can also use 1.5mm Viton rubber sheet. Do it right, do it once

Hylomar is excellent to smear on gaskets or replace them on precision joints but not sealing a fuel tanks or not so good joints.sunrisemac wrote:Blue Hylomar is fuel resistant
In a past life I worked for a company that made re-fueling riggs for the F1 industry. We found NO silicone that was truly petrol resistant, in a sheet form or liquid. It would always breakdown, go soft and fail. We would also use good old cork or nitrile sheet, and where possible we would joint with nitrile O rings.
