Yamaha Drive² Fleet Fuel Pump Hose & Line Routing

The gasoline Yamaha Drive² Fleet golf cart uses an electric EFI fuel pump with a pressurized supply line from the tank area to the EFI system. There is no crankcase pulse hose in the EFI pump circuit.

How the Yamaha Drive² Fleet fuel lines are routed

Confirm the exact gasoline model year/engine and use the matching service or parts diagram before disconnecting the pressurized fuel line.

Relieve residual fuel pressure using the official procedure and disconnect battery power before opening the EFI fuel circuit.

Trace the pressurized supply from the tank-area electric pump toward the injector/throttle-body assembly; there is no crankcase pulse hose in this circuit.

Inspect quick-connect fittings, O-rings/seals and EFI-rated hose/line for damage, kinks or abrasion.

Preserve factory line clips and routing so the fuel line stays clear of exhaust heat, sharp edges and moving drivetrain components.

After reconnection and priming, inspect the pressurized line and tank/pump connection carefully for leaks before operating the vehicle.

Common Drive² Fleet hose-routing mistakes

Low-pressure hose on EFI

Use EFI-rated hose, fittings and seals; low-pressure carburetor hose may be unsuitable.

Damaged quick-connect

A damaged retainer or O-ring can leak under pressure.

Kinked pressure line

A restriction can reduce fuel pressure and cause hesitation or no-start symptoms.

Poor factory routing

Lines or wiring routed near exhaust heat or moving parts can be damaged.

Drive² Fleet fuel hose and line layout

Pump/system: Yamaha EFI electric pump.

Engine/system: 357 cc Yamaha EFI gasoline.

Routing: Tank-area electric pump → pressurized EFI fuel line → Yamaha EFI injector/throttle body.

Applies to: Drive² gasoline EFI.

Model-specific note

Yamaha's current Drive² gasoline specifications identify EFI with a Yamaha-built 357 cc engine. No crankcase pulse hose is used in the EFI pump circuit.

Yamaha Drive² Fleet fuel hose FAQ

How is the Yamaha Drive² Fleet EFI fuel line routed?

On gasoline versions of the Yamaha Drive² Fleet golf cart, the tank-area electric pump supplies the EFI system through a pressurized line toward the injector/throttle-body assembly.

Does the Yamaha Drive² Fleet 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 Fleet 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 Fleet 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 Fleet 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 Fleet EFI fuel line be secured?

Preserve the factory clips and routing so the line remains clear of exhaust heat, sharp edges and moving components.

Verify with official documentation

Fuel-line routing, pump type, connectors and pressure requirements can vary by model year, engine and serial range. Before disconnecting or replacing any line, confirm the routing in the official owner, operator, parts or service manual for your exact Yamaha Drive² Fleet.
