Without me pulling up the manuals the shop manual or the Haynes manual here on the website to find pictures to circle and post I would say the fattest line is your main line the next to the fat ass line is your return and the skinniest line is the vent and that thing you have circled is just an anti rollover valve in case you flip your vehicle it won't spill gas on the highway which I don't imagine you care about nor do I so I got rid of it just bypass it.

MazdaMitch either way i feel like if you flip the truck it would spill out i appreciate the help dis you unhook it from the truck frame or just plug it off

MazdaMitch do i just plug off the rollover valve line?

MazdaMitch

Mini_Truckin_Brandon I can't remember what I did but I think you can just bypass it. Take it out of the loop you know what I mean?

I'll know more or refresh my own memory when I do that on my project truck.
