Fortunately the only thing wrong with the vehicle was a snapped drive belt which knocked out the alternator and water pump. Limped it to my local garage and hopefully it will be fixed by tomorrow. It is a 12 year old Renault savannah which has served me very well for many years and has cost virtually nothing to run over the years I have had it, so it really does not owe me anything. Mrs A. says that I have to keep it until it dies though!
Jeff, we can get exactly the same taps as the one that your customer has fitted for you. They come in several versions:
Female to female BSPP screw thread (1/8", 1/4", 3/8", 1/2")
BSPT Male to BSPP female screw thread (1/8", 1/4", 3/8", 1/2", 3/4")
BSPP Male to BSPP female screw thread (1/8", 1/4", 3/8", 1/2" and also male 1/4" to female 1/8")
BSPP Male to male screw thread (1/8", 1/8" to 1/4", 1/4", 3/8" to 1/4", 3/8", 1/2" to 3/8", 1/2")
They are not that cheap though at about £9-10 each.
