E-Z-GO RXV 4 Fuel Pump Hose & Line Routing

The gasoline E-Z-GO RXV 4 uses different fuel-line layouts across model years. Newer EX1 EFI versions use a tank-mounted electric pump and pressurized supply line, while earlier gasoline versions can use a low-pressure pump layout.

Identify first

Find the exact year, engine and serial/model code.

Earlier low-pressure

If your year is carbureted, trace tank → pump → carburetor plus the pulse line.

Later EFI

If your year is EFI, trace the tank pump → pressurized line → injector/throttle body.

How the E-Z-GO RXV 4 fuel lines are routed

Identify the exact model year, serial/model code and gasoline engine before moving any hose or fuel line.

If the vehicle is an earlier carbureted version, trace tank supply → pump inlet → pump outlet → carburetor and identify the separate engine pulse/impulse line when fitted.

If the vehicle is EFI, trace the tank-area electric pump to the injector/throttle body through the pressurized supply line; do not add a crankcase pulse hose.

Do not copy routing from a different year simply because the model name is the same.

Match hose pressure rating, connector style, seals and routing clips to the exact fuel-system generation.

After service, prime/start the vehicle as appropriate and check every disturbed connection for leaks.

Common RXV 4 hose-routing mistakes

Wrong-generation diagram

The same model name can span different gasoline engines and fuel systems.

Pulse routing on an EFI cart

EFI electric pumps do not use a crankcase pulse hose.

EFI hose on an older diagram

Do not assume newer connectors, pressure ratings or module layout apply to older carbureted versions.

Missing year/serial check

Use the exact serial/model code before ordering hose, fittings or pump parts.

RXV 4 fuel hose and line layout

Pump/system: EX1 EFI or earlier gasoline system.

Engine/system: Generation-dependent gasoline.

Routing: Newer EX1 EFI: tank electric pump → pressurized line → injector; earlier gasoline versions can use a low-pressure pump layout.

Applies to: Multiple gasoline generations.

Model-specific note

The RXV 4 was sold across more than one gasoline fuel-system generation. Match the routing to the exact model year and engine before disconnecting lines.

E-Z-GO RXV 4 fuel hose FAQ

Does every gasoline E-Z-GO RXV 4 use the same fuel-line routing?

No. The E-Z-GO RXV 4 name spans gasoline generations, so the correct routing depends on model year, engine and fuel-system type.

How do I know which E-Z-GO RXV 4 hose diagram to use?

Identify the exact serial/model code and gasoline engine first. Then use the matching official parts or service diagram.

How is an older carbureted E-Z-GO RXV 4 typically routed?

Where a diaphragm-pump system is fitted, the usual path is tank to pump inlet, pump outlet to carburetor, plus a separate engine pulse/impulse line.

How is an EFI E-Z-GO RXV 4 routed?

An EFI version uses a tank-area electric pump with a pressurized fuel line to the injector/throttle-body system; it does not use a crankcase pulse hose.

Can I copy routing from a different-year E-Z-GO RXV 4?

Not safely without verification. Pump type, connectors, pressure rating and line routing can change even when the model name stays the same.

What should I verify before replacing E-Z-GO RXV 4 fuel hose?

Confirm the exact year/engine, fuel-system type, hose pressure rating, connector style, seals, routing clips and fuel compatibility.

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 E-Z-GO RXV 4. For current documentation, visit the official manufacturer website.
