An electric fuel pump can be fitted if the stock mechanical Fuel Pump goes bad. Carburetor applications call for 4 psi max, so using a low-pressure pump is recommended.
Contents |
Overview
Advantage:
- Easy to troubleshoot
- Primes the carb fuel bowl
Disadvantage
- Extra wiring needed
- Noisy
- Danger of fire in a crash if pump keeps pumping fuel. For safety fit a crash relay.

Mitsuba
Mitsuba Part Number FP-3
EFI Fuel Pump
Electronic Fuel Injection generally requires a medium-pressure or high-pressure pump.
See main article: EFI for A-series engine
Wiring
The fuel pump is best wired up with a relay.
Holley universal Fuel Pump Relay kit $107
An oil pressure safety switch can also be fitted to cut power to the fuel pump if the engine stops.
Holley Safety Switch $29
Mr. Gasket 7872 $16
The switch is installed where the normal oil pressure switch goes by installing a T-connector.
There are also more sophisticated relays that take a TACH signal and crash sensor to detemine when to cut off the power.
DIY
- 16-gauge wire for the HOT side (RED or whatever color you want)
- 16-gauge wire BLACK for the earth/ground side
- 10A Fuse (or circuit breaker?)
-
- Relay of minimum 10A rating, get a reliable OEM unit like this common Nissan part:
-
- Connect short length of HOT wire to the BAT + or ALT + (your choice)
- Fix fuse to this short HOT wire, to protect the rest of the new wiring
- Then more HOT to the Relay (D). Keep the wire as short as is feasible
- more HOT wire from relay to the fuel pump connector
- Fix BLACK from new pump connector to a body ground or engine block
- connect small wire (20 gauge is fine) from IGN circuit of the original wiring hanress to relay. Connect it to one of these:
- points ignition: 12V side of the coil resistor
- electronic ign: + side of the coil
- anti-diesel valve on the carburetor
- Connect small black wire to ground relay switch (E). Can ground it to:
- body, or
- engine block
- To prevent corrosion, seal all the wire connection ends with a sealer
Improved Pump Relay Circuit
Factory Nissan circuit sees 3 relays. Allows pump to run when starting, and automatically cuts off if oil pressure fails.
RELAY-1: pump power relay RELAY-2: normally closed IGN to Power relay switch RELAY-3: sensing relay. Oil pressure falls, grounds Relay-2
Because ACC is OFF when key=START, fuel pump is powered during START.
Uses two diodes. The dual-purpose oil pressure switch is for the S110 with Oil Pressure Gauge instead of oil lamp.
- 25070-P8000 SWITCH ASSY-OIL PRESSURE
Datsun 1200 does not need this switch.
Inertia Safety Switch
An inertia switch can also be fitted to cut power in a crash.
[http://www.rockauto.com/catalog/x,carcode,1133288,parttype,10756 STANDARD MOTOR PRODUCTS/Intermotor FV7 Universal $70}
Junk yard can net one cheap:
1990 circa Ford ($50.87 New). Mount with button up.
Mount on a steel panel, like the kick panel or firewall.
After a bump, pushing on the reset button causes the linkage to reset itself.
