#513, "RE: great thanks for the info!" In response to In response to 5
My Bell Eng FPR is about a 4" diam disk. From the idle adjustment screw to the tip of the fuel in/out ports is ~6". It's an odd shape, but it fits rather well where the relays are located. The fuel lines can hug the firewall and go behind the winsheild washer fluid container. I'm using 1/4" fuel line, it works just fine. Good luck...
