I have a 292 Y block and a 352 FE block.  Both appear to use the same fuel pump.  Is there a difference on the fuel side?  I would think a 352 or 390 would consume fuel at a faster rate but have not found anything on this.  If the pump arm and diaphragm are the same, the only thing that could change is the check valves.  Are the fuel pumps interchangeable????

Thanks for any help,
