Anyone know where I can find a schematic for a F 12 fuel pump. My pump has no markings on it other than made in USA. It is a 1934 model.
 
For your information, fuel pumps were used on F 12's from 1932 till 1939. The later model was a F 14 which was built from 1938 to 1939..
 
I'll be darned. I thought they were gravity flow like the H's and M's. Learn something new every day. Were they mechanical or vacuum?
 
F-12 Farmall had their own engine built by International Harvester. There were no Chevrolet or GM engines. They had a fuel pump and a down draft carburetor/
 
The carb on those sits on top of the intake, about 1/2 or more of the way up the fuel tank. Downdraft with a funny governor housing going to it.

I've been around them,but I never worked on one. That's something I'll have to look at next time I see one.
 
I think its the same fuel pump used on the w-9 tracotors too. They were a-c fuel pumps . Steiners has rebuild kits for them.

The F12/14 fuel pumps were made by AC ( as in AC Delco) this site has rebuild kits for the two styles used, one has the diaphragm peened on the shaft and one has it attached with a locknut
