I just know somebody out there has done this. I am helping my son repair an antique engine fuel pump and a replacement is not available. The diaphragm is dry rotted but the check valves and everything else are fine. I tried NAPA yesterday and called Mcmaster-Carr and they could not help me find diaphragm material. It is a rubber impregnated cloth probably Buna-N (Nitrile) or something like that. The fuel pump is real easy to get to and there is a telltale there in case the diaphragm does rupture so I am willing to take a shot on most anything. I am almost tempted to try a piece of fire hose I have in my shop. The original one is peened on but it looks like an easy matter to grind off the peen and tap for a screw. Any thoughts would be appreciated. Thanks.
