830 Injection pump

GarlicFarmer · Jun 30, 2017

I have replaced the bad injector on my 830, I have fuel to pump but # 1 & 2 will not squirt fuel and 3 & 4 seem a little weak. Would there still be an air lock prior to pump? Its a 1967 case o matic

Fuel enters the injection pump gallery at the rear, bleed orifice is at the front next to # 1. There's still some trapped air in the gallery that needs to come out before the plunger barrels will fill correctly. Leave all four lines loose, then crank the engine with throttle open until you see air free fuel at each outlet. Use the decompression lever if engine has one so the starter does not have to work as hard during bleeding.
