 |
|
Hey Guys,
I'm going to make a couple fittings for the bottom of my fuel tanks...
( see "rough" sketch below )
The two pieces of Stainless steel will be concaved to make a low point
in the tanks... this way I can put a gasolator and drain and fuel pick-up at the lowest point of the tanks ( I might add a "site gauge" too )
My question is...
What are some good Gasket materials....Both Hard & soft ?
.

I've revised my sketch...I'm thinking of making the "inside piece" slightly
smaller to force the curve a little better....
I'm thinking of going with "thicker" material and just tapping the holes
instead of welding nuts on (TIG)
Gasket seal ????? Hard , soft , silicone stuff ???

Hey Guys,
Here's a few pictures of what I've got so far....
I didn't like the way the concave seal was turning out...
So I went for flat Washers.... I'm gonna "groove" them later to get the
Fuel pick-up as low as possible....
I also went with 8 screws instead of 6....
BUT.... I "STILL" am looking for some kind of gasket material that can be
used with gasoline.....The Silicones that I've read say "NO Gasoline"
I'm wondering about cork....?
Well,
Here's a few pictures...

Mike/Gang:
Everybody wants to do it their way, and I understand that. However,
there is another solution to installing outlets in the bottom of
plastic tanks, which I am assuming you are doing.
It is a very simple metal elbow and a neoprene washer that pushes into
a hole drilled into the bottom of the plastic tank. They work very
well, last for years. I have some in a 15 gal plastic gas tank I used
for hauling fuel for my FS 20 years ago. It is still usable.
Compared to the hardware you have come up with it weighs next to
nothing for a set of two for two tanks.
I am sure Travis, at Kolb, has them in stock. Tell him hauck sent
you. Will not help, but tell him anyhow.
Take care,

Hi John,
Those fittings were talked about before....what we didn't like about them is they don't drain "all" the fuel / water / debris ...
They stick up from the bottom of the tank aprox 3/8"
I'd rather just put a gasotator on to filter and Drain/Check the fuel/water....without anything accumulating in the tanks....

Another point is that when they do begin to leak, it creates a messy,
unpleasant and potentially dangerous situation. After I learned this from
experience, I plumbed my new tanks from the top, they way they set up the
new ones. Why make holes in the bottom of your tanks when you don't have
to?

I have been using the same fittings that John Hauck is talking about for 15
years in the bottom of my tank and I never had one start leaking yet and I
have a tank that has a bubble in the bottom where I put it so I get a good taste
of water on my preflight once in a while ( I hate it when it doesnt warn me
when the gas starts to get on my toung ) but I got all the water out snip snip
