On gasoline versions of the Cushman Truckster XD utility vehicle, the fuel pump is typically in the gasoline fuel-supply system near the tank/engine service area; exact pump mounting should be checked in the model-year service parts information.

Where is the Truckster XD fuel pump?
Typical location: in the gasoline fuel-supply system near the tank/engine service area; exact pump mounting should be checked in the model-year service parts information.
Before ordering: Truckster XD is also sold with a diesel engine; this page applies only to gasoline EFI versions.
How to replace the Cushman Truckster XD fuel pump
Truckster XD fuel pump specs and hose layout
Fuel system: EFI on the gasoline Truckster XD.
Fuel-line layout: Pressurized EFI supply on the gasoline Kubota engine.
Pressure: EFI system; exact pressure is model/engine-specific.
Check these before buying a fuel pump
Pump power: Check the applicable fuse, relay, connector voltage and ground before condemning an electric pump.
Fuel pressure: A pump can run audibly and still be weak. Compare measured pressure with the correct service specification.
Filter / strainer: A restricted filter or in-tank strainer can cause low pressure and poor acceleration.
Tank vent: A blocked vent can restrict fuel delivery even when the pump itself is healthy.
Connector condition: Look for heat damage, corrosion, loose terminals or moisture at the pump connector.
Truckster XD quick check: If the pump receives correct voltage and ground but fuel pressure remains below specification, the pump or in-tank restriction becomes the main suspect.
Truckster XD fuel pump troubleshooting
Cranks but will not start
Check pump power and ground, then verify actual fuel pressure instead of relying only on pump noise.
Starts then dies
Measure fuel pressure and inspect the tank vent, filter/strainer and pump electrical supply under load.
Weak under load
Low fuel pressure or a restricted filter/strainer often shows up first during acceleration or climbing.
Fuel leaking
Do not run the vehicle until the tank seal, fuel line or connector leak is corrected.
Cushman Truckster XD fuel pump FAQ
Where is the fuel pump on a Cushman Truckster XD?
On gasoline versions, the fuel pump is typically in the gasoline fuel-supply system near the tank/engine service area; exact pump mounting should be checked in the model-year service parts information. Truckster XD is also sold with a diesel engine; this page applies only to gasoline EFI versions.
How do you replace the Cushman Truckster XD EFI fuel pump?
Relieve fuel-system pressure, disconnect battery power, unplug the pump electrical connector and fuel line, remove the tank-mounted pump/module and seal, then install the correct model-year replacement and leak-check the system after priming.
What fuel pressure should the Cushman Truckster XD have?
EFI system; exact pressure is model/engine-specific. Use the exact model-year service specification before condemning the pump because pressure can vary by engine and generation.
Should I hear the Cushman Truckster XD fuel pump when I turn the key on?
On many EFI systems the pump runs briefly to prime the rail, but operating strategy can vary. Pump noise alone does not prove correct pressure, so measure pressure if the engine still has a fuel-delivery symptom.
Why would the Cushman Truckster XD fuel pump have power but still not deliver enough fuel?
A worn pump, restricted in-tank strainer/filter, poor ground, voltage drop or blocked tank vent can let the pump run yet still produce insufficient pressure or flow.
What should I test before replacing the Cushman Truckster XD EFI fuel pump?
Check the applicable fuse and relay, verify voltage and ground at the pump, inspect the connector and fuel line, then compare measured fuel pressure with the correct service specification.
Fuel-system design, pump type, location and specifications can vary by model year, engine and configuration. Before ordering parts or servicing the fuel system, verify the details against the official owner, operator or service manual for your exact vehicle.
