My boat is a 1978 Columbia 8.3. I've been boating only 3 years now. The engine is a Universal M4-30. The injector pump
is not pumping. Am trying to find specs. online. Everyone says to have an expert rebuild a bad pump
, it's too difficult for an amateur. I have the pump
off the engine now and pretty much have to repair
it myself due to financial considerations. Does anyone know anything about this pump
? Where to find schematics if nothing else? Would be very grateful for any info. Thanks.
