Can I use "right stuff" permatex for sealing the gas tank shut off unit , below the tank? It says oil resistant but nothing about gas...Thanks, Paul
Use Fuel Lube. Dan
Without an experiment, I don't know, but I doubt it. Gasoline acts as a solvent and I'm sure that it will soften up any RTV if exposed to gasoline long enough. Jim Patrick

Is it the threads you are sealing? If so, yellow teflon tape has always worked well for me. No mess!
I said something to the effect that Right Stuff was RTV and several posters ripped me another one.
RTV will not hold gasoline back, except in one small part of Texas, and I don't know about right Stuff.
Supposedly Permatex 2 and 3 work quite well at sealing against gasoline.
I have used it, it says on the container it will seal gasoline.
Paul,
To answer your question, no the right stuff is not ok for gas sealing.

Pematex #2 is good for gas.

I used Permatex #2 to seal the bulb to the bottom of my new fuel tank, and 6 months later it's seeping.
I looked on the tube (actually on another blister pack in the store) and it indicates gasoline, but not alcohol.
I suspect good old Permatex has met its match in the new fuel.
I'm going to try and find some yellow Teflon tape. I've never seen it, but there's a plumbing supply house on the way to Lowe's - I hope one of them has it.
If not, any other ideas?
Try an auto parts place such as NAPA or Auto Zone. Jim Patrick
RTV silicone does not fully set up in the presence of gasoline. Use Permatex.

We used to use a product called "Gasoila" back in the sixties to seal gasoline leaks. I don't know if it is still available, or if it works with modern gasoline. Just a thought. Dave
Thanks for the input, guys. the yellow tape works but the permatex stuff won`t hold up to gas exposure. There isn`t much stuff offered for sealing gas leaks/ fittings--just ordered a 5 oz tube of "fuel lube" (thanks, Dan) and will give this a try. Thanks for the posts, Paul
K&W Copper Coat says it's safe for gas on the label.
I used it on mine with good results so far, but it's only been a month or so.
Wide variety of gasoila products. Widely available. Just google it.

This looks like "Eseal" is what you'd want for gas with alky.

Last week I purchased a roll of yellow tape from Lowes ( plumbing department ) in Toronto. It is readily available
