A few more questions

[prodjay10]

Is there a gasket between this fitting and the fuel pump?

What is the thread pitch and size of the distributor holder?

What is the thread pitch and size of the fan pulley?

Is cylinder one on the front passenger side?

Not sure what you are asking on the fuel pump.   There is a gasket between it and the engine block.   IF its the style with the internal fuel filter there is a gasket on the 'nut' that holds the filter into the pump.   The other connections are flares or barbs so no gaskets there.

The threads in question I think are 5/16-24 know as a 'fine' thread.   Other 5/16 places on the engine are the coarse 18 threads. 

Yes cylinder 1 is front passenger side which is not at all common for American engines of the era.

Thanks for your help. I found the filter and gasket, but the gasket is toast. Where can I find a replacement gasket?

You may be better off making one yourself. That one will make a good template.

NAPA has what is called "carburetor fuel inlet" gasket assortment.  Places that do carburetor overhauls will have it, and it is in multiple places online if you search Rochester Quadrajet fuel inlet gasket, and it will show 7/8" and 1" ID gaskets.  I know that you are saying this is on the fuel pump, but if the gasket ID is the same, the above sources will do the job.


Edit:  After looking again at the fuel filter retainer and gasket, that looks like some special gasket that is thicker than a paper gasket.  Does it go just under the hex portion of the filter retainer or does it go over the "nose" of the filter retainer?  Also, did the filter have a spring behind it to hold the filter against a sealing surface?  Just some more questions to "muddy the waters".

I found a large enough seal that worked. Not the same but close enough

I guess that we'll have to deduct a few authenticity points!
