Hi Steve , that sounds like a plan but like you the noise drives me mad and the pump doesn't seem to stop pumping.I have heard of a pump that fits somewhere at the rear of the vehicle which might cure the noise problem.Does your pump and regulator fit in the engine bay? I don't suppose you could send me a picture of your layout?

I'll take some pics of the install tomorrow but my pump is in the boot and the reg is under the bonnet where I can reach it easily to adjust it. TBH they both came with the car so I have no idea of make. The pump, though rubber mounted on 2 "cotton reel" mounts, is still really loud in operation and, unlike the better SU pump, runs almost continually as yours does.
This may be due to the install, as electric pumps come in 2 "shades" a) short suck, long blow, designed for mounting, near the tank and b) long suck, short blow, designed for mounting near the engine. I postulate the possibility of an equal suck/blow pump for mounting centrally under the floor but i've not seen one. But if you mount the wrong pump in the right place (or vice versa) it will overwork itself and wear out quickly. Since I don't know which sort I have (and the previous owner was an incompetent bodger) I may have the pump in the wrong location!
I'm actually half inclined to splash some cash and buy a "proper" SU type pump which are only really noisy when priming the carb(s), once running they subside to a gentle occasional tick, rather than the constant thunderous drum of the one i've currently got! Maybe one designed for an MGB would do the job to an acceptable standard and noise level!

EDIT, a quick scan of ebay has produced prices of £100+ for genuine or good quality lookalke SU pumps, I may have to think again!
