I need some help with installing my TPIS fuel lines for my MiniRam intake. Which TPIS hard line goes to which factory line, and which fuel rail? How do I tell which factory line is supply/return? Pics would be great!
one sure fire way to know which is which.
follow them back and find the one that has the inline fuel filter (mounted on frame) thats the supply line, it connects to the passenger side fuel rail.
the return line goes to the drivers side AFPR.
