Am deeply disappointed, Richard, I thought that lying on one's back on a wet road trying to hit the SU pump with a spanner was surely part of the pleasure of early Mini ownership?
Saying that, the fuel pipe did one day spring a leak and sprayed fuel onto the exhaust manifold, in the middle of Loughborough, setting light to the insulation I had rashly installed under the bonnet to aid me in listening to my tape player whine as it played. It taught me to always carry an extinguisher - which later proved its worth when my Dyane caught fire in Sutton Coldfield...
I would hesitate in connecting a fuel pump feed anywhere close to the coil, the last thing one surely needs is to replace a fuel issue with an ignition related one.
