The great thing about old cars and bikes is that if you listen to them, they often will tell you what's wrong. I've developed a fine ear for subtle changes in sounds. My 53 was getting cranky, and it occurred to us "where's the tick tick of the fuel pump?" It had slowly become less frequent. Check power to the pump, no issues there. Let's pull the points... you can actually do that without removing the pump. They looked like they had been through a house fire. A quick clean and re-install, and it's TICK TICK TICK TICK TICK... Really happy pump, happy car. When was the last time you checked your fuel pump points? They corrode over time, simple fix. Video Before and after...   | ||

Nice, I bet that has been responsible for quite a few stoppages. Easy fix though  | ||

Joe, if the points are really bad, they can be filed so much that the top removable portion can't make contact past the edge of the pedestal. For anyone reading this. There have been many heated discussions made over on the Jag forum about the unreliability of the SU pumps, but I've never had a problem with them. Once rebuilt properly, they can and do go for decades. I've always believed that if they fail after servicing, someone did not know what they were doing. Some replace the old capacitor with a diode, Varistor, or some such thing to keep the points from arcing _ it can be made non-polarity sensitive with the correct part. |
