Original metal gas tank?

[BigB9000]

I currently have the Attwood Wal-Mart gas tank for my 1970ish 6 HP
The previous one wouldn't pick up fuel anymore, the one prior to that the fitting attachment fell apart, and my newer one has Attwood's quick-disconect on it. Which is far from easy or quick.

Im thinking about cleaning up one of the metal ones I have.

They look pretty simply.
Looking at the parts list for them, doesn't really seem to be any wear parts, maybe a new gasket
0310984 GASKET,Housing to tank
Maybe a new vented gas cap? (0763525)

Thoughts? Metal better? Ive never seen someone use one of these, don't know why though. It came with the motor, should work right?
Or is there a reason people stopped using these?

A lot of the steel tanks get rusty and start to leak. Usually the leaks are on crimped seams and are hard to fix. Is your tank rusty or are there oily gas stains around the seams?

Ahh, forgot about the rust factor.
Here in SoCal, you don't usually have to inspect for rust.

Looks like just bit of surface?

Rig some way to pressure test it up to about 3 PSI. If it holds, fly with it. The cap gasket is probably about shot, seems to be the first thing to go on these old tanks.

Those older steel tanks are the best in my opinion.---Seen a lot of poor quality on the fuel pick-up tube on plastic tanks.----Where you plug in the hose on the metal tank there are 2 small pins .--These are valves.---One lets fuel out and one lets air in.----East to pop out the plugs to replace the o-ring in there.
