Thanks everyone
Problem fixed - one of the relays is dead, car running fine with a temp replacement. Ordered two as you suggest. (with diode).
Out of interest my fuel pump is in the back on the slanting (45') bit of the tank.
There is something on the top of the tank - not sure what thats for - any one know??
Thanks for your quick and accurate responses/solutions.
I'm on a very steep Morgan learning curve.
Cheers
Chris
