One way Check valve for installing in many gas/diesel/bio fuel systems where you desire fuel to only flow one way. Opening pressure approximately 1psi. This is a simple one way valve designed to keep fuel from backing up. Not intend to hold back higher pressure, but seems to hold up to 20 pretty well.

Both sides are for 8MM or about 5/16" lines.

Note: Other sizes and colors available in our other auctions.

Stops stubborn leak back problems that may cause hard starting. This valve is designed to put inline where rubber hoses are used. Be sure to install it so the fuel can go in the direction desired. I have seen many a hard starting problem cured with one of these items.
