Yes sir.

Started plumbing up the surge tank, new rail, feed and return lines and other stuff today. It's not finished and the cable ties are only to hold things in place while we measured to get the right length of braid etc and won't be there when it's all done. All done with proper bulkheads in the boot and teflon braid so as to sto as much fuel smell as possible.

Big thanks to Steve from Steve's Speed Shop and BezerkR32 for their assistance.

looking good mate

any reason you havent used a larger return line? and did you use the very top (vertical) fitting for the surge tank feed or return to tank or return from engine?

Im asking this cause ive yet to do my setup (the tank has been mounted for months in the car though lol) and everyone does it slightly different

Hi Mate - the return from the engine is -8AN which I think will be plenty large enough. It's the top-most feed in the side of the tank. The feed to the surge tank (just below the return from the engine) and overflow from the tank back to the main fuel tank (very top fitting) is -6AN.

Here's the shots of the two new -8AN lines run to the front and the tidied up boot setup. A lot less cable ties (there are almost none now) and looks a lot neater.

I now see why you were scared of the bill lol

O-rings in the Indy injectors were too big for the intake. New o-rings and wiring to go.

Have to plate up the IAC on the plenum as it won't clear the rail. Also have to plug up the feed to it from the pipe pre-throttle body.
