Injector Pump Leak Perkins 4.236
I have a 4.236 with a CAV injector pump that leaks around one of the injector line connectors. It's very hard to tell but it looks like it's leaking between the connector and the bottom of the pump. I have tightened the bolt to the point where I'm afraid to strip it or twist it off. I have also replaced the washer but it still leaks even though the fuel is not under pressure. Anyone have any ideas?
