Gas Drain Plug Leaking

I would def try some gas sealant on the threads. Go simple first.

 

you may use not the aluminum sealing ring, take a material what is softer, copper for example.
you are sure it leaks from there? never had this before

 

Hylomar Universal Blue on the threads. Great stuff.

 

yes, great stuff, mostly when it goes into the fuel pump if you use too much

 

Wow, you must have really globbed it on. Only takes a bit to seal. I would not use it on high pressure connections, as it never dries.

 

Hylomar- real old fashioned stuff, a right pain when it gets into lines or filters if you use too much.
Some great loctite products about these days.
Hylomar was designed either by rolls royce or designed for them i believe- been in use over 50 years i think

 

I often use hylomar, but only there where the gaskets have to be removed later again. and that is so easy then. on all "paper"valve cover gaskets at a ferrari I use it both sides

 

Its fine provided you can get it the parts assembled before it dried. It was no use in engine rooms as too hot. Considering it has been made for so long it is doing well , against the modern products.
