You should not have to alter the wiring to the pump.

If the pump is the original type ELECTRICAL one (with points) then it will work either way. However, if it's the more modern ELECTRONIC version then you'll have to get a negative earth version or change back to the original type.

Just consider radios, washers etc before you go ahead.

But - you WILL need to clean the points on the pump. They will have 'hill + crater' effect from running +ve earth, when you change over this will reverse, so to avoid trouble - make them flat !
