I have an aluminum fuel tank mounted on the bed of my truck. On the roll over valve I put a -8 an 120 degree fitting and -8 an line to a bulk head fitting in my bed. When I brake and the tank is 1/2 full or more fuel spills out thru the roll over valve. Is there a -8 an female to a -8 male one way check valve I should be using or is my installation wrong. Can anyone direct me?????
