Metal lines and rubber and nylon hoses transport fuel, vapor and vacuum to the various components in the fuel system. Gaskets and seals prevent leaks and can also block unwanted air, dirt or contaminants from entering the system. These parts are typically overlooked, but they can be the cause of problems, and their replacement is often necessary when other components are serviced, which is why you’ll find an extensive inventory of them on our digital shelves.

Metal tubing attached to the underside of the vehicle with clips routes fuel from the tank to the fuel pump and carburetor or fuel injection assembly. In areas where there is movement between components and flexibility is needed, such as between the engine and chassis, rubber or nylon hose is used but it must be fuel resistant to prevent deterioration, non-permeable to prevent the escape of vapors, and reinforced to withstand pressure in fuel injection systems.

In addition to fuel delivery, metal tubing has been used on older vehicles to conduct heat from the exhaust manifold to the choke coil, and connect the distributor vacuum advance unit with an engine vacuum source. Non-permeable rubber hose is used throughout the EVAP system to conduct fuel vapor. Nylon and rubber hose is used to connect many components in the engine control, emissions control, climate control, and other systems, including the MAP sensor, EGR valve, fuel pressure regulator, brake booster, PCV valve, and thermal vacuum switches.

Metal lines are generally connected to components and each other with threaded compression or double flare fittings, or quick release fittings that require a special tool to disconnect. Fuel resistant O-rings are used at many connections and these should always be replaced once the fitting is disconnected. These O-rings are also used to seal connections at fuel injectors and pressure regulators. Several types of clamps are used to secure hose including spring-type, worm drive, and clamps that must be crimped with a special tool during installation. Spring type clamps lose tension once removed and should be replaced.

Gaskets seal connections between the throttle body or carburetor, between the plenum and lower intake, and at the manifold/cylinder head junction. Old gaskets can harden and crack, resulting in vacuum leaks that cause a lean condition and rough idle. If a vacuum leak is suspected, vacuum hose should also be checked for cracks and breakage. Metal fuel lines should be regularly inspected for excessive corrosion and any signs of leakage, as well as kinks and dents that could restrict flow. Rubber hose should be checked for cracks, abrasion, and sponginess. Any fuel leak is dangerous and should be repaired immediately.

    How To Replace An In-Tank Fuel Sending Unit
    A Fuel tank sending unit is a term for the mechanical assembly inside your fuel tank which measures the level of liquid in the tank, then reports its findings to the fuel gauge on your instrument cluster. All sending units contain a "float" piece which does just what it describes - floats atop the surface of the fuel. Many automakers design the float piece as an attachment on a hinged arm that pivots as the level in the tank rises or drops. Others design the float piece as a cylinder that rides up and down around a metal shaft.

VW Fuel Line
I purchased a high pressure fuel line for my 1980 VW, and CARiD was the only place I could find the line. The dealer did not even have it. The line arrived in a few days, and was the perfect fit.
