Universal fit. Can be used on practically any application requiring a check valve. Also great for water pressure pumps & galley pumps which are not self-priming. This valve prevents fuel from returning back to the tank and keeps it in the fuel line, so if you have a vehicle that is hard or slow to start because the fuel is returning back through the lines this will solve all your problems. Professional grade non-return valve - Ideal for marine, automotive, recreational vehicles, and agriculture. Safe to use on gasoline, diesel, and 2-stroke motors. Easy install. Cut the line where you want to install the valve. Insert the lines onto the valve and install the clamps. Make sure the arrow on the valve is pointing in the direction you want the fluid to flow. Fluid will not flow in the opposite direction of the arrow. For example, in a fuel system you will want the arrow to point away from the fuel tank and towards the carburetor. Made by Muzzys and available in (3/32", 1/4"), (5/16"), (3/8"), and (1/2") ID inner diameter sizes in my other listings.
