Mercury Pressure Tank

[Buccaneer]

Trying to get this pressure tank fixed up to use with my 1953 Merc Mark 15.
Installed a new diaphragm, but the primer didn’t want to work good enough
until I made a new discharge check disc valve. It still wouldn’t keep the motor
running, as I think the tank isn’t building up pressure.

I suspect the pressure relief valve and / or the gas cap seal.
The graphics on the tank are still “decent”,
so, I’d like to use the tank. anyone ever mount an OMC head on the Merc tank?
Six of the eight bolt holes line up, but the last two on the end are about 1/16″ off.
If a person made up a new “backer plate” to go inside of the tank, to match
up with the OMC head, I think it would be a “go”.
