Welcome to SU Fuel Pumps and More, a collection of articles and information about the SU fuel pumps used on a variety of British cars, primarily, but not limited to, MGs, as well as an assortment of articles I’ve written on the care, maintenance and enjoyment of MGs, especially the T-series MG and the MGB.
A little bit about me . . .
The above picture is where it all started. In 1974 we purchased a 1953 MGTD, ostensibly because I had always wanted one to replace the one I had in high school. Actually, the car was pressed into service as a second car that my wife could drive – and drive it she did. For 7 years that was her everyday car to haul groceries, the kids, the dog, lumber, everything.
After a month of so of driving it, the fuel pump started acting up and I fussed with it a bit and got it running – I thought. After several more tries to keep it running, I came home one night to be met at the front door by an irate wife pointing to the garage and saying FIX THAT D****D THING – it had quit 13 times on her, coming across town (a distance of about 8 miles). The next day, I pilfered a big power transistor from work, mounted it outboard of the pump and ran wires into the pump and got it running – and it stayed running. Next I went to Radio Shack, got a small epoxy power transistor that would fit under the end cover of the pump, made a permanent installation and then wrote an article in our local Register’s newsletter, complete with drawings and directions on how to make the modification. It seems that most people in the Register wanted me to do modifications for them. Over time, word spread and I got more and more pumps. I found a better way to modify the pump using a magnetic trigger so I could eliminate the points completely, and finally have gone to an optical trigger to get away from magnetic interference.
Now it is 2008, the kids are grown and gone, and I am retired – I am still doing the fuel pumps, we still have the TD and my wife and I love to dance (see picture below) and go on cruises. If you want me to restore your fuel pump, I only work on them from October 1st through June 1st each year. The rest of the year is for getting home projects done and going on cruises. The dancing goes on all year long.
