Ok so I put the check valves in and it seemed to work but didn’t completely fix the problem. Then I put a new pressure regulator in and it stopped transferring the fuel back and forth for about a day or so and now it does it again. Is there...
Ok. Do you know a place where I can get high quality check valves? I don’t want to get one and it break a month after I buy it. If you were putting these on your truck is there a certain brand you would use? Thanks for all your help.
