Recommended sealant for fuel tank sender...?

[max and caddy]

Recommended sealant for fuel tank sender...just got a shiney new sender for the pick up, its a diesel (TDI in fact ) and i see there was some sealant on the studs and the gaskets are a bit old and well..y know...so hylomar blue? or is there a better product i could use?

Would say that's ok but the loctite flange sealant for engines might be better would use the best you can get u don't really want to be going there again

i do have some loctite sealer in a syrige thingy...its VW stuff like silicone and black..could this be it?

Its VW supplied stuff but is loctite 5970...says on the tube "not recomended for immersion in petrol" but i guess diesel is not petrol so maybe the very stuff? what you think?

after i had discovered that i had some of the infamous batch of seals ( the ones which dissolved in petrol) for my new sender unit last year, i put the original seals back on. i wanted to beef them up with a fuel proof sealant and was recommended Wellseal which i think is shellac based. i have had no trouble since.
The guy who recommended it restores classic cars and motorcycles and always uses it for fuel related assemblies.

well seal it is then! i didnt like the silicone idea as it might be a bit too permanant!

Interesting link to MLC in Preston, I think my engine man may get his Reinz gasket kits and so-on from there...
