If 1G26 is the date code it is a July 26, 1961 pump up for a rebuild. All else in the kit seems to be correct but it looks like I have a diaphragm for the vacuum pump. Going to have the main body opened up for 3/8" line.
Were there factory fuel canister type AC fuel pumps with 3/8" lines?
Were factory 391 fuel pumps rebuildiable AC pumps? (That would solve the main body issue.)
With the factory rocker arm and pin position is there any other way to get more volume?
