This 28 minute on demand video manual will take you through the step-by-step procedure for taking the upper (motor section) of a short MFI fuel pump apart and replacing three o-rings that are prone to hardening and leaking fuel. The upper section is not as prone to leaking as the lower section, but if you are going to open up one of these pumps, Kent recommends you replace ALL six seals. If you purchase the reseal kit both videos are included free. See related products below:

These early “short style” electric fuel pumps are very prone to leaking fuel because the rubber case o-ring seals harden with age. New pumps are no longer available and rebuilt are VERY expensive! If you risk buying a used one it will probably end up leaking or seeping fuel too.
