The fuel pump is located on the right side of the engine block. Original pumps are made by Kyosan Denki.



  • 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

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



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

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:

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