Fuel Pump

The fuel pump is located on the right side of the engine block. Original pumps are made by 京三電機株式会社 (Kyosan Denkiᴳ) the fuel pump specialists, a member of Denso Group since 1969.

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
