I just ran home and snapped a couple of pics. Like I said I used the stock Vortec lines from the fuel rail and cut them where they transition to soft lines.
I used Earls fittings from Summit Racing (-6 AN to 3/8) to hook up to the fuel filter then the same fitting to new 3/8 line stopping where the original ones did.
before I got my fuel cell I just went to the hardware store and got a 3/8 compression to barb fitting. I used regular worm drive hose clamps and they didn't leak but I would recommend FI clamps.
The stock YJ supply line is 5/16 and so is the Vortec return, just use the Jeep supply as a return and run new supply line from the t case back to the tank. You don't even have to drop the tank to hook them up.
