Which fuel line to where?
 

i think I have it right but there is a small problem making me think I have it wrong. 2 steel lines on passenger fender in engine compartment for returns to tank, right? 3rd line from below, between starter and passenger fender fuel delivery to filter then to pump right?

By the way, I got the truck with the engine already pulled so I never took the hoses off, which is why I'm unsure what is what.
