Specifications
Original Datsun 1200 (1970-1973) * 2.6 psi * 450 ml/minute minimum flow rate
That's good for 96 hp.
Late pumps: * 2.8-3.0 psi * 1300 ml/minute minimum flow rate
Testing
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.
Nissan repair kit comes with new diaphragm & valves
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.
Fuel Pump Blank
Nissan part is commonly available and inexpensive.
EFI Fuel Pump
Electronic Fuel Injection generally requires a medium-pressure or high-pressure pump.
