Overview

• All 1966-1973 pumps interchange (front distributor engines)
• All 1974-2007 A12/A14/A15 pumps interchange (mid-distributor engines)
• A10/A12 pumps are lower pressure output (2.6-2.8 psi)
• A14-A15 pumps and some A12 are 3.0 psi

Sealed top late 1970s

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
Album 26310

Album 14123 Album 27235

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:
Album 24005

Interchange

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

Album 18149

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).

Album 8023

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.

Part Numbers

Original 1200 fuel pumps are rebuildable and have five screws holding the cast top to the chamber
