I would think that you wouldn't want too thick of a gasket since that will change the position of the arm on the camshaft. Which of course is not a good thing.

The NOS gasket out of gasket set 373678 for 356 engine is .084 or just slightly less than 3/32.
The composition is a very compressed material, fairly hard, and doesn't seem to bend like cardboard usually does. You can sort of see the layering. Don't know if this one has just gotten hard or if it is something special. I would think if you found that approx thickness at the parts store, the composition the mfg of the gasket selected would be OK. Most all of the paper or composition material should resist heat a bit. Attach file:  (26.25 KB) (38.33 KB)

BDeB, Turbopackman, and HH56 --- Thanks for the input. Searching my memory it seems to recall that the gasket was not a paper type, but thicker and made of different material as described by BDeB and like the one HH56 is showing. Eric, taking your point about a gasket being too thick, a gasket thinner would mean changing the stroke of the fuel pump lever the other way. Your point is well taken. Thanks guys. Now, where to find one ...

This was always exactly like the gasket on my '54 Fuel Pump. It's almost like a thin plywood. Similar to what you would find at most hobby stores.

Rat's... my rebuilt pump came with a thin gasket. I will have to search for a thicker gasket locally. Great discussion everyone.
John, I really enjoyed your article in the last PAC news Bulletin; great story.

39super8, in an earlier discussion about insulating gaskets, sleeves, and washers O_D commented about how critical the gasket thickness on the 3-piece straight-8s is. If I recall correctly, a gasket much thicker than is used on the mono block 8s is needed. I am sure someone here knows all about it and can advise you. Thanks for the compliment on the article. It is a fun story to tell so I decided to write it and submit it for publication. I did this months ago and guess that Craig finally ran out of things to publish. It is nice to see it in print. Thanks. (o{I}o)

John, yes that is correct. Both of my 3 piece engines have the thick phenolic fuel pump insulator blocks. The 356 seems to get a thinner gasket in comparison, but not paper thin as in the one HH56 posted and Kevin confirmed. Been feeling under the weather, so not making as much progress as hoped for. Did manage to get the oil cap primed and sanded now prepped for paint. Was there a reason to get this picky with an oil fill cap, no not really. Just something I could do in spare time. Working on coming up with a thicker fuel pump gasket. Should have something in hand tomorrow with any luck. Hoping to take out for a drive this weekend if all progresses as planned.

Finished up some odds and ends on the car today. The finally was a nice long ride. The car performed very well. If the lifter pumps up I will have exhaust and intake manifold gaskets and if the lifter doesn't, I will have a head gasket to do also. Need to go out at night and aim the headlights. Other than that, it's off to the cruise in Friday and Saturday night. Next Sunday is our annual orphan car, car show. Hope to make it.
I also discovered while setting the timing the vacuum advance is inop. P.S. funny thing, I just had the nagging feeling the horns needed to be installed and operable. What do you know, on the first trip out, some dunce pulls out in front of me. Horns work! LOL Attach file: (43.61 KB)
