I have a 03 reg cab that is bagged . I am switching out my parallel 4-link to a triangulated 4-link which means the stock gas tank has to go. I already made brackets so that it will mount behind the axle on the two crossmember/supports i fab'ed up. My question is what needs to be done in order to move/lengthen the sending unit back 4 feet. Can I just get longer fuel lines and extend the connector. I am kinda a noobe when it comes to this. Alos could someone explane the lines to me. looks like an in/out fuel line dont know what the other is and what the connector is for? Sry for this long post any help is appreciated. Thanks
