Blackstone fuel pump rebuild kit

[jimTN]

The diaphram in a Blackstone is just a sheet of rubber or some sort of rubber fabric. It pumps with pressure from the air side of the pump. I once had a instruction sheet and over the years have lost it. If anybody out there knows which push rod and length of the rod to use with which pump I would appreciate it. I have a couple of those pumps.

in my knowledge the original push rod based on your engine should work , tiny and short for 59A and bigger on 8BA but not sure 100%
