Firstly I watched the YouTube post from University Motors that was superb to re-build the pump. I almost got there then accidently touched the wrong part of the breakers with my battery to test it, should have put the plastic cap back on and blow out, literally, the top contact breaker........I was so angry with myself I ordered a new electronic SU unit from Victoria British, who are great!
FYI I had about three seasons of trouble free motoring, this year seems like one thing or another has gone wrong........starter, front brakes, front suspension re-build, fuel pump......still love the '72 MGB though.
