Information on the product

Non-return valves are frequently used when retrofitting veteran and classic cars to prevent fuel tank and line leaks. Installation examples can be found in the text. We now stock 10 mm and 12 mm fuel check valves.

Motorservice has revised its range of fuel check valves and now also offers fuel check valves with 10 mm and 12 mm connection diameters.

Fuel check valves are installed in fuel lines. They allow fuel to only flow in one direction and prevent lines running dry, for example.
