Hi Dave, sorry can't help with the references at the mo, I think they are on GoMog (?) but I had a non starting car and replaced the fuel relays with brand new Bosch units in Lucas boxes, still no joy despite attempts by a mechanic and an auto sparkie. Had to do a Factory visit and they got it running within minutes with their Chinese made relays!
Apparently the Bosch units disintegrate on the shelf with age hence my problems.
