Here is all the gasket numbers anyone could ever need ... except head and exaust gaskets .
Form-a-gasket Ultra Gray. You put a thick film on both sides ... wait 10 minutes , put the two pieces together finger tight ... wait 30 minutes , then tighten to your spec.
Never leak , made to fit , and easy as can be !
Don't make the "Thick Film" thick enough to squeeze out too much , but just a little . The putting together finger (lightly) tight and waiting is the most important part ... you can wait a whole day before drawing it tight if you want a "thick" gasket.
