Repair

The original fuel pump is easy to repair. You can generally take them apart, clean it, then put back together using the original gasket.

Leaks

A low pressure value might be due to a leaking gasket. It will definitely cause a fuel smell.

Finger-tighten these bolts in case they are loose:

Interchange

Note that early A-series and late A-series fuel pumps differ:

Pumps with the long arm fit 1974 and newer A12/A13/A12A/A14 and A15. Pumps with the short arm only fit A10 & A12 front-distributor engines (1966-1973).

Electric Fuel Pump

An electric fuel pump can be fitted if the stock mechanical pump goes bad.

See main article: Electric Fuel Pump

EFI Fuel Pump

Electronic Fuel Injection generally requires a medium-pressure or high-pressure pump.

See main article: EFI for A-series engine

Part Numbers

Original fuel pumps are rebuildable and have five screws holding the top chamber, and one central screw fastening the disc-top.
