Thanks , My question is how do I know if it is a cav? I know it is a minimec and I am guessing that is a Simms, the inspection cover is on the side and i can see the fuel rail and when we checked the oil in the pump none came out of the plug hole that shows full..we filled the resevior up with oil and cleaned out some gunk in with the fuel rail and tried to some degree to move the fuel rail , but stopped until we had some more info..it is a 3cyl. and they are inline on top of the pump..
