M38A1 Fuel Pump

[rick25]

I was able to start my M38A1 today - the first time its been run in 26 years!

The carb has been rebuilt (thanks Casey) and the engine will run and idle great but only when I pour fuel into the bowl through the vent line as there is no fuel supply making it to the carb.

I've plumbed all new fuel lines and the tank is clean so I decided to check the fuel pump which has been sitting dry for years.

I disconnected the fuel pump "inlet" hose and connected a vacuum gauge to find that I'm not even drawing 1" of mercury. Is there some way I need to prime the pump or are the diaphragms shot and I require a rebuild kit?

Thanks,

Rick
