On gasoline versions of the Cushman Shuttle 8 people mover, the fuel pump is typically at the fuel-tank/engine service area under the seat; current EFI platforms use an electric high-pressure fuel-supply system.
Shuttle 8 • Gasoline versions
Where is the Shuttle 8 fuel pump?
Typical location: at the fuel-tank/engine service area under the seat; current EFI platforms use an electric high-pressure fuel-supply system.
Before ordering: Current Hauler, Shuttle and Refresher Oasis gas versions use EFI, but older model years can use different systems.
How to replace the Cushman Shuttle 8 fuel pump
Shuttle 8 fuel pump specs and hose layout
Fuel system: Closed-loop EFI on current gasoline versions; older versions may differ.
Fuel-line layout: Pressurized EFI fuel line with pump electrical/relay circuit; do not use pulse-pump hose routing unless the exact older version is carbureted.
Pressure: 43.5 psi (3 bar) is documented on current Textron EFI platforms such as Hauler XL; verify the exact model/year.
Check these before buying a fuel pump
Identify the system: Do not order a pump by model name alone when the same model spans carbureted and EFI years.
Carbureted versions: Check the pulse hose, filter, tank vent and suction hose before replacing the diaphragm pump.
EFI versions: Check fuse/relay, pump voltage and ground, filter/strainer and measured fuel pressure before replacing the electric pump.
Fuel hoses / lines: Inspect for damage, restriction, air leaks and previous repairs.
Tank vent: A blocked vent can cause fuel starvation on either system.
Shuttle 8 quick check: Identify EFI versus carbureted hardware before testing or ordering parts, because the two systems use different pumps and diagnostics.
Shuttle 8 fuel pump troubleshooting
Cranks but will not start
Identify the fuel system, then test pulse/fuel flow on carbureted versions or pump power/pressure on EFI versions.
Starts then dies
Check the tank vent and filter first, then test the system-specific pump input and output.
Weak under load
Low EFI pressure, a weak diaphragm pump, a leaking pulse hose or a restricted filter can all cause load-related starvation.
Fuel leaking
Stop running the vehicle and repair the leaking hose, fitting, pump/module seal or tank connection.
Cushman Shuttle 8 fuel pump FAQ
Where is the fuel pump on a Cushman Shuttle 8?
On gasoline versions, the fuel pump is typically at the fuel-tank/engine service area under the seat; current EFI platforms use an electric high-pressure fuel-supply system. Current Hauler, Shuttle and Refresher Oasis gas versions use EFI, but older model years can use different systems.
How do you replace the Cushman Shuttle 8 fuel pump?
First identify the model year and fuel system. EFI versions use an electric tank-area pump/module; older carbureted versions use a low-pressure diaphragm pump with inlet, outlet and pulse connections.
Does every Cushman Shuttle 8 use the same fuel pump?
No. This model family spans more than one fuel-system generation, so the correct pump depends on model year, engine and whether the vehicle is EFI or carbureted.
How can I tell whether my Cushman Shuttle 8 is EFI or carbureted?
Look for an injector/throttle-body EFI system and an electric pump connector at the tank on EFI versions. Carbureted versions use a carburetor and typically a three-line pulse/diaphragm pump.
What fuel pressure should the Cushman Shuttle 8 have?
43.5 psi (3 bar) is documented on current Textron EFI platforms such as Hauler XL; verify the exact model/year. Confirm the exact model year before testing because carbureted and EFI versions use very different fuel-pressure ranges.
What should I test before replacing the Cushman Shuttle 8 fuel pump?
On a carbureted version, inspect the pulse hose, filter, tank vent and pump output. On an EFI version, check fuse/relay, voltage, ground, filter/strainer and measured fuel pressure.
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.
