A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. The fuel rail is the last distribution point in the fuel system before fuel is sent to the injector. In return-type systems, fuel is returned at a lower pressure than that found in the feed line or fuel rail. In non-return systems, the fuel rail serves only as a distribution centre for all the fuel it receives.

What You'll Learn
- Fuel lines are hoses or pipes that transfer fuel from one point in a vehicle to another
- They are made of rubber and can be cut to length as required

- Fuel lines can be replaced and upgraded as required
- They are defined by the United States Environmental Protection Agency as all hoses or tubing designed to contain liquid fuel or fuel vapour
Fuel lines are hoses or pipes that transfer fuel from one point in a vehicle to another
Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburettor on the engine. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
In return-type systems, fuel is returned at a lower pressure than that found in the feed line or fuel rail. The fuel rail is the last distribution point in the fuel system before fuel is sent to the injector. Each fuel rail is connected directly to the injectors that it feeds and relies on a fuel pressure regulator to relieve excess fuel pressure. The regulator maintains fuel pressure based on intake manifold pressure and routes the excess fuel back to the fuel tank.
Some builders will replace sections of flexible line with “hard lines”, usually aluminium tubes bent into straight lengths with large radii that run along the firewall and undercarriage. This offers the greatest protection from high line-pressure failure and offers the least amount of maintenance.

A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. They are made of rubber and can be cut to length as required. Rubber fuel lines are flexible and are used to connect the fuel pipes on the chassis to the fuel pump or carburetor on the engine. However, they have a tendency to perish over time and can rub through if not properly secured.

The regulator maintains fuel pressure based on intake manifold pressure and routes the excess fuel back to the fuel tank. In non-return systems, the fuel rail serves only as a distribution centre for all the fuel it receives; feed pressure is regulated by an in-tank regulator before being sent to the fuel rail so there is no excess fuel or fuel pressure to return to the tank.

A feed fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another.

These rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.

A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. The United States Environmental Protection Agency defines a fuel line as "all hoses or tubing designed to contain liquid fuel or fuel vapour". This includes all hoses or tubing for the filler neck, for connections between dual fuel tanks, and for connecting a carbon canister to the fuel tank.
