So i just got a new 20 gallon tank and sending unit for my 91 YJ Jeep Wrangler. I installed my tank with sending unit but stupid me, i cant remember which line goes to which sending unit valve. I know one line goes from the fuel filter but not sure which valve it goes to. Can someone help this country girl who'd love to get out in the woods with her jeep to do some mudding/trail ridn before winter time?

I am planning on upgrading my 4cylinder 2.5 engine but im not sure which way to go. I use my 91Jeep Wrangelr YJ for mudding and playing around. I want more power. Id really appreciate if anyone could give me some ideas on what to upgrade to and approximate costs.
Thanks
