Does it matter which Fuel Pump polarity I order?

Yes and No!

If you intend to purchase an original style `points` type pump then it is not important as we have recently made steps to ensure that all 12 volt `points` pumps are dual polarity. This means that whether you order positive or negative earth, you will receive a replacement, dual polarity version.

If you are ordering the later `pointless` type pump with the electronic switching then it is still important to make sure you have selected the correct polarity for your vehicle. This is because the circuit board used in the production of these pumps is hard wired to either positive or negative and can not be changed.

All electronic SU fuel pumps have a suffix of either `EN` for `Electronic Negative`, or `EP` for `Electronic Positive`. Unlike the standard `points` type fuel pumps, the part numbers for these pumps do not contain a space between the alpha and numeric codes.
