Merc 3.0LX - Fuel Pump Gasket

[MikeDobbs]

I'm replacing the fuel pump in my Merc 3.0LX engine, and the new Sierra pump comes with 3 gaskets. Am I supposed to use all 3? Does it depend on the engine?

Engine Serial #: 0K277779

I couldn't post a picture, so here's a link to a website showing the pump and 3 gaskets:

I think some of the engines and fuel pump configurations used multiple gaskets to get proper fuel pressure

Would mimic what’s there
