Re: [OMC-Boats] Gas tank question

I did the same thing.  I believe the gasket material I used was ~1/8" cork material and I just cut the pattern carefully around the opening and bolt holes.  It ran all last year with no issues.

Btw, I  "Renu 'ed" ( http://gastankrenu.com/ ) my tank last year  for $275.  They clean it and coat it with a sealant inside and out.  Looks and works great.  Mine had a fair bit of rust on the bottom,  inside and out, but was still structurally sound.  I had mine done at B&B Universal Distributors in Detroit, but there are places all over the US that use the same process.  I'm so happy with it I'm thinking of pulling the tank on my 1966 Galaxie 7-litre and having it done too.

I miss the list  The forum is nice, but I never think to check it.  Out of sight, out of mind, I guess.  I hope everyone is doing well!

I had mine apart back in '04 because it was leaking badly from around the
top flange.  I vaguely recall some sort of RTV-like sealant on some of the
screws, but that might just be because you mentioned it now.  In general,
RTVs don't work with gasoline, so I doubt it was doing much.  When I
reassembled my tank, I didn't use any sort of sealant on the screws.
Instead I used this stuff:
   http://www.farmandfleet.com/products/443210-fiber_gasket_material.html?lref=%2fcatalog%2ffind.aspx%3ft%3dgasket%2bmaterial
and cut a new gasket in the shape of the flange.  In principle there could
still be a little bit of leakage around the screws, but I haven't seen that
happen - I've had no problems with leakage (never did a pressure test, but
I keep that area clean and have never seen signs of gasoline residue).

If you want to use some sort of sealant, Dow #730 RTV is supposedly
gasoline resistant (though outrageously expensive), or you could try
Permatex 56521 thread-sealant, which claims gasoline resistance.
