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.
Nissan
Stock on 1982 Datsun 720 pickup with air conditioning:
- 17010-A7600 NISMO High Volume Nissan type "Transistor"
-
- 7 psi, requires regulator when used with regular engine
- 1.3L/min (at P = 29kPa, 3.0kg/cm2), Diameter = φ60, Length = 140 mm, Inlet Shape = Diameter φ8, Outlet Shape = Diameter φ8, Electric Consumption = 7.0 A, Electromagnetic piston type for carburetor, With insulator
- 16404-29900 Replacement Filter
- 16420-E0100 Blanking plate (for A-series engine fuel pump) $12.08 USD
-
- W0133-1601714 Nissan 720 OE Service Fuel Pump
- Nissan
-
Aftermarket
Rockauto - Airtex universal kit
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
- 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 miniumum10A 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
