In this guide
If your Grizzly loses power while towing, climbs poorly or becomes difficult to start, investigate the whole fuel-delivery system before buying a pump. The same symptoms can come from contaminated fuel, a restriction, wiring trouble or an ignition fault.
Confirm the replacement fits your Yamaha Grizzly 700
Our matching product listing covers YFM700 applications in the 2007–2016 range and references 3B4-13907-10-00. This is a starting point for checking the part, not a guarantee for every variant in that range.
- Record the exact model code, model year and market variant.
- Check the original part number in the manufacturer’s parts catalogue or through a dealer; account for any superseded numbers.
- Compare the connectors, outlet arrangement, mounting points and supplied components with the listing.
- If anything differs, send us the model details and clear photos before ordering. Avoid removing the pump just to look for a number if the catalogue can identify it.
Symptoms and what to check
| What happens | Useful next check |
|---|---|
| Engine cranks but will not fire | Fuel condition, fault codes, ignition and fuel pressure |
| No expected key-on pump sound | Fuse, control circuit, power and earth at the pump |
| Hesitation or power loss under load | Fuel pressure, restrictions, electrical supply and ignition |
| Trouble changes with fuel level or slopes | Fuel level, pickup arrangement, venting and connections |
These are directions for diagnosis, not a parts-replacement verdict. If the engine does not crank normally, use our motorcycle no-start checklist before investigating fuel pressure.
Working quad checks: contamination, connectors and load
Make a note of whether the fault occurs cold, hot, under load or after storage. Inspect accessible wiring for rubbing, loose connections and signs of water ingress. Check fuel condition and the tank-vent routing using the model’s manual. Dust or water contamination needs correcting as well as the failed component; fitting a new pump into a contaminated system can leave the original problem unresolved. Do not use a towing job or steep slope as a diagnostic test.
How to confirm a fuel-pump fault
Use the workshop manual for your exact model. There is no single pressure value, pinout or test procedure that is safe to assume for every quad. A useful diagnosis checks the pressure against specification and the pump’s electrical supply under the prescribed conditions. Low pressure with correct supply still requires checking restrictions and the pressure-control arrangement before replacing the pump.
Fuel-pressure testing needs a correctly rated gauge and the specified adapter. Do not loosen a pressurised line to see whether fuel comes out, bypass safety circuits or improvise an exposed battery connection near petrol.
Replacement planning
This is an overview, not a substitute for the model-specific removal procedure. Petrol and its vapour are flammable. Work with the engine cool, good ventilation and no ignition sources. If you cannot depressurise the system safely or do not have the correct tools, use a qualified workshop.
- Follow the manual’s pressure-relief and battery-isolation sequence before disconnecting fuel lines.
- Clean around the assembly and remove the specified panels or tank components without straining hoses or wiring.
- Inspect the tank and filters for contamination, and resolve its source.
- Compare old and new parts. Use the correct seals and follow the specified orientation, tightening sequence and torque.
- Reconnect the lines and wiring, then perform the prescribed priming and leak checks before refitting covers or operating the quad.
Do not ride if there is wet fuel, a persistent petrol smell or an unresolved leak.

Frequently asked questions
Does a humming pump mean it is healthy?
No. Noise confirms some activity, not adequate pressure or flow. Compare measured performance with the model’s specification.
Does every Grizzly 700 use the same fuel pump?
No fitment decision should rely on the Grizzly badge alone. Confirm the exact model code, year, variant and original parts reference against the listing. A similar-looking assembly can have different connections or specifications.
Should I replace the pump just because the quad stalls?
No. Stalling can have fuel, electrical, ignition or mechanical causes. Record the conditions, check fault codes where supported and test before ordering.
