A car with a steady fuel leak isn’t going to run for very long and it isn’t going to be pretty when it burns to the ground. With that realization, I was more than happy to send my leaking fuel pump to Arthur Gould for a professional rebuild. I was happy that I did this for a few reasons. Gould’s work is fast, efficient and relatively economical and I can rest easy knowing that a critical component on my car was rebuilt by someone who does fuel pump rebuilding as a living. Turnaround time was under three days and the $90 I spent was a wise investment considering a rebuild kit is over $45. As a bonus, the returned pump is absolutely gorgeous! It’s amazing what a little bead blasting, new hardware and clear coating can do for looks.
Gould reported back that my pump had two major flaws. First, the diaphragm was stretched out allowing fuel to pass from the top chamber, through screw holes and into the body of the pump that is not supposed to see any fuel. Second, a portion of my pumps actuating foot was broken off. The broken piece held the return spring in place. While the foot would have probably worked ok, the return spring could have fallen out at some point rendering the pump inoperable. The solution was to find a new pump core and Gould had plenty to sell.
