Ha! I think I might have been responsible for starting him on the road away
from VB. I had no end of issues with carpet, tonneau, and rubber. Most didn't
fit. What fit was poor quality. Then when I ordered a servo from them, it was
the last straw. I bought their "kit" because for the same money as SS I got the
servo and installation mounting kit. Once I got it, I found out the mounting
pieces were garbage and the servo was the wrong pressure ratio (1.9:1, where
Rick sold the 2.3:1 and stock was actually closer to 3:1). But that's another
story.
I'm going to rebuild the SU on the car - and do it with my son. Only fitting.
Thanks for the info.

Subject: Re: Rebuilding the SU Fuel Pump
Hi Jay:
The original SU pump, as you have found by now, uses points to carry the
current to the pump (that's the ticking you hear when you turn on the
ignition). The current is pretty hefty and, therefore, the points get
eroded gradually with time and eventually give up the ghost. There are
suppliers who will rebuild the pump and convert it to solid state (see
below). The points still switch the current but it is greatly reduced
so that the points will last indefinitely and the pump will be very
reliable, as a result. I have had such a pump in my Tiger for probably
25 years with no problems. The original pump carried the SU id AUF301
but that has been replaced by AUF303, IIRC. Victoria British lists an
electronic replacement for the MGC (3-074) which I think is the correct
pump. I know your Dad didn't like VB stuff so FWIW. Moss Motors also
lists SU electronic pumps for the Big Healey and some of them used the
same pump as the Tiger.
Here is a link to a guy who will do the conversion if you want to go
that route. I have no connection with him, just found a link to his site:

Good luck,
