I am in the process of restoring a 52 Hornet convertible and have a question, as I don't know what I am doing. Does anyone know the correct length of the bolts attaching the 308 Carter Single Action fuel pump to the block? I pulled the pump to rebuild it and when reinstalling it noticed the pump was mounted on top of 5 stacked gaskets and there are 4 washers on the bolts. I am concerned these are not the original bolts and the extra spacing was to keep them from hitting the cam? Or perhaps the gaskets were to move the lever arm away from the cam for some reason? Any help is appreciated.
The gasket stack is proper. For every gasket you take away, you increase the fuel pressure
So it impacts the lever arm and ultimately the diaphragm travel? Would you suggest just replacing the gaskets with the same height of gaskets, having nothing else to go on?
When we buy a full gasket set for a rebuild, it includes a setup for the fuel pump that is stapled together. I thought the stack was four gaskets, but it could be five. I install the stack, dry. Any time after the rebuild that the pump needs removed or replaced, I use the same stack, if the new pump didn't come with one. The mounting bolts usually have thin phenolic sleeves to insulate heat transfer through the bolts to the fuel pump body. If these are missing, you will notice the bolts are pretty sloppy going through the pump base. The gaskets can be replaced with a stack totaling the same thickness, as you suggested.
Paul Schuster sells the fuel pump gasket stacks and may also have the sleeves for the bolts.
