Thanks for the suggestions, I've ordered the Smiths Sender Unit BHA 4711 and I'm going to temporarily extend the existing wiring so that I can sit comfortably in the driver's seat and try both of them to determine any differences in their function etc before finally fitting to the tank.
Luckily a long time ago I cut a circle in the back seat floor pan above the sender unit to allow easy access then fitted a covering plate., so fitting and removal is very easy peasy.
I'll let everyone know of the final outcome and any and all adjustments necessary to mimic the original. I'm very grateful to both Nigel and John for the useful input.
Cheers
Dave
