Yamaha Drive² Concierge 6 fuel hose FAQ
How is the Yamaha Drive² Concierge 6 EFI fuel line routed?
On gasoline versions of the Yamaha Drive² Concierge 6 people mover, the tank-area electric pump supplies the EFI system through a pressurized line toward the injector/throttle-body assembly.
Does the Yamaha Drive² Concierge 6 EFI pump use a pulse hose?
No. The EFI pump is electrically driven, so it does not use the crankcase pulse hose found on older diaphragm-pump systems.
Can a kinked fuel line cause Yamaha Drive² Concierge 6 problems?
Yes. A restricted pressurized line can reduce fuel delivery and cause hard starting, hesitation or power loss.
Can ordinary low-pressure hose be used on a Yamaha Drive² Concierge 6 EFI system?
Use fuel line, fittings and seals rated for the exact EFI pressure and fuel type specified for the vehicle.
Why can a Yamaha Drive² Concierge 6 fuel line leak after pump service?
Check the quick-connect, O-ring/seal, retaining clip and line condition. Do not operate the vehicle with a pressurized leak.
How should the Yamaha Drive² Concierge 6 EFI fuel line be secured?
Preserve the factory clips and routing so the line remains clear of exhaust heat, sharp edges and moving components.
