ScottyDoggs and Fordman77 thanks for the information !!
I am in the middle of the work now, I have everything apart.
I am doing some other things while I am in there .... changing heater hoses,
plugs, wires and all injector O-Rings.
I do have a question about 3 O-Rings that were included in the UIM gasket set.
Where do these go ? Where what look like 2 "grommets" on the gasket side of the SC ?
See the photos I attached....
