500 EFI T-stat Housing Assembly?
 

Upgrading my 500 MPI's to 500 EFI's.

Trying to figure out ho9w the 500 Efi t-stat housing is supposed to be setup? I didn't have one to reference, as everything was in pieces.

The service manual shows it 2 different ways ( whoever wrote the service manual was held asleep - never accounted for a lot of the changes from an MPI to Merc Racing setup).

Anyway, my thought is:

1) the round grounding gasket is on the intake.
2) Manifold Casting next
3) brass insert into the top of the casting
4) cork gasket
5) T-stat - spring down?
6) gasket with bypass notch?
7) Y cap
