This was problem.s from before I bought the boat. The fuel regulator just pops out with the removal of a c clip and the pop in a complete new unit from volvo. No mystery to it my pressure is in spec with the service manual. I have the return line system and POS fuel cell Volvo puts out

as bup already said,their is no regulator on the fuel rail,that is a pulse dampener.the fuel rail is the same one used on a pickup truck with a 8100 engine.it is very common for the fuel rail to rust on the inside.bup schooled me on this several years ago when i was working on one of these engines.just a fyi,michigan motors sells new injectors for the 8100 engine for 262 bucks delivered to the door through ebay,i just bought a set of eight for one i am replacing the fuel rail&injectors on.

early to mid 496's 3 hole pintle later years used a 4 hole pintle. But Merc If I recall now went to an all 3 hole pintle injector replacement for all . Merc list these for 358 PER ONE injector. Too high way to high.

something not right with Michigan Motors offerings Yes they have 8 so called 496 injectors shipped for 262 but then they have as well. I believe these are the real marine Delphi for the 496 apps .

Will add Michigan Motors really knows not much about fuel injection. I have stores about their customers buying brand new engine packages that would not run correctly. They MM - were clueless why MPI engine buyers of their products were going into guardian mode with warning horn faults after installing their brand new drop in repowers. I knew why and I can go into details about this if needed. I was the one whom discovered why and I'm sure MM fixed it by now after all my findings.
