Cheers Jim, Yes I am using the original tank. I don't have an LP pump at the moment so will have to source one. I will have a look at the scrapyard tomorrow morning and see what suitable donor I can find for the pump. If I put a low pressure pump in will I be able to leave the HP pump mounted on the bulkhead?

Once it's primed it will lift higher but if that fuel drains out or you run out of petrol you will have to prime it again. So it needs to be below the level of the fuel in a near full tank. Have you got a low pressure pump at the moment ? Have you still got the original carb petrol tank ?
