If you're lucky enough to have an original Carter X fuel pump on your car, you're truly among the elite in the Mustang world. Why, you ask? Because the X pump was used only on the Boss 302 and 429, the 428 and 429 Cobra Jets, and the Super Cobra Jet. Today these pumps bring very good money, especially if someone needs this piece to finish off his or her vintage performance restoration.
In his recent purchase of a 429 SCJ Mach 1, Bob Myhrer got one of these pumps. Problem was, it was leaking badly--the sign of a ruptured diaphragm. Fortunately for Bob, AMK carries a repair kit that can fix up the old X good as new.
