My cousins have an F-12 that used to belong to our Grandfather. It has started leaking gas out of the fuel pump.
I notice the S- vendor carries kits for them so I'm assuming they are rebuildable. Is there anything a person needs to know in order to do that?
Does anyone sell replacement pumps?
 
They are available right here on YT. They just come apart and go together. Remember ethanol is not methanol. Methanol is very
destructive of rubber, neoprene, and composites Ethanol is far less reactive and can be ignored in fuel. Jim
 
Rick, the diaphragm shaft come to ways riveted end or a replaceable screw. I don't know of S or YT kits.
But after you take the diaphragm out and look at the shaft.
I get mine from Frank at Rice equipment he has both styles.
Also ask about what is in the kit. I have seen basic and major kits, so it depends on how fare you want to go.
 
The rocker arm in my pump was severely worn and had been built up with weld. I managed to find a new replacement, using the AC part number, which is 855547.
