Here is a write up I did for another member last night asking questions, thought I would post some of the things I did for a nice install. Every car is a little different, as I mentioned in other threads I come across an issue at the rail where the 90* fitting was touching the intake and has some clearance issue. it is a nice out of the box setup, and short of shimming the rail like I did, not sure there is another solution.
hi Steve, I left the old lines in place, they dont hurt anything. Me as well did this laying on my back. It was good that you contacted me now as I was just doing some maintenance so I took some pictures. Ask questions about the pictures and their orientation.
Start from the back at the fuel pump and work the lines over the back seat frame area
Mount the filter on its side on the lower seat brace on the floor board.
Run the lines up the frame
Take the transmission linkage brace off the proportioning valve and stuff the lines behind it, then put the brace back on. It helps hold the lines back.
I zip tied the lines together at this point, used self infusing tape to hold the lines together as well as used two layers of heat tape and zip tied it to the brake lines, I wanted the fuel lines as far away as possible to the header. The self infusing tape is like silicone that provides insulation as well as a nice semi-sticky surface for the heat tape to adhere to.
I ran the lines up the front of the engine. The return comes up and beside the accessory bracket. I would take the alternator off as well as the tensioner. I havent yet found a better way other than going behind the the tensioner bracket and pinching the line in between it and the bracket. You will see the geometry how the lines come up and go to the fuel rail that there is not a better way...that I can come up with. As mentioned in my threads I had to shim up the fuel rail a tad to make room for the 90* fitting to fit under the fuel regulator.
Feed line is simple, just find a best path and run up to the rail, zip tie it down to keep away from turbo. There is a heat wrap that comes with it, make sure it is on the feed line.
