Bottom Line Up Front (BLUF): What gasket material can I use for making a cover gasket? I'm thinking of using Fel-Pro Karropak 1/64" (Fel-Pro 3045). I measured the old gasket at about .0135" to .0145". I would imagine Packard used gaskets measured in fractions of an inch. 1/64 = .015625.

I was surprised I could access the pump for removal and re-installation by leaning over the fender. My blower is not installed. While the mounting bolts are removed, rotate the pressure regulator to 6 o'clock for removal and re-installation

The pump drive has 12 slots so I guess every slot moves the rotor 30 degrees. With the engine at 6 degrees BTDC and the vacuum canister at 9 o'clock I believe the rotor should be at 7:30. Each cap position is separated by 45 degrees. On the next pump slot the oil fill tube interferes with the vacuum line. On the previous pump slot the grease cup obscures the distributor securing screw. This is related to the 30 and 45 degree choices I guess.

I need a new gasket for the cover and thought I'd make one for convenience. It is Packard P/N 303930 I believe.
