My son and DIL own a 60s Ford truck that they use for a catering business. There is a Holley Blue fuel pump mounted to the inner fender. The pump is spraying fuel from the gasket between the upper and lower pump bodies. A new pump is about $200 and I'm wondering if anyone knows if there are rebuild kits for these pumps? I found kits for other pumps, but not this one which is a 12-812-1.
