engine and drivetrain Fuel Pump Gaskets?

[eastsidebimmer]

I'm prepping an engine and there is a gasket between the head and the insulator block for the fuel pump. I can't seem to locate a part number for this gasket although it can be seen on this diagram below, are there supposed to be two gaskets, one for each side of the insulator? Any idea the part number? Thank you people. -Ben

order the insulator - the gaskets are bonded to it already

really important is the plastic inserts (#3) in the mounting holes

of the pump sliding over the studs, then 2 flat washers, and finally

2 Nyloc nuts - without the plactic insulators (#3),

washers and Nyloc nuts =

the pump comes loose very quickly
