While driving a 55 Clipper Custom the engine will shut off. When I finally coast to the side and stop, I can restart the car with no problems. This happens randomly. I have gas, new battery, good wires, rebuilt motor, pertronix ignitor ignition, replaced all spark plug wires, coil, new cap and rotor. Any ideas?

I had the same problem with both of my 1955 Packard Clippers. I went to Carquest and found that a Master M fuel pump #6866, which fits a Chrysler 318 early 70s, bolts right in. I drive in Phoenix, AZ elevation 1200 feet and at the north Rim of the Grand Canyon elevation 8800 feet and had no problems. You can get a cross reference at NAPA for the same part. I only paid $16.50 and it has a lifetime warranty and since I plan to keep the car a long time I hope the company is still in business when I need to replace it. I have put over 30000 miles on this fuel pump.
