The braided fuel line comes off a fuel regulator mounted on the inner fender skirt. I'm using an-6 fittings made by Sniper. The FL then goes to a billet aluminium fuel filter with a 40-micron filter screen. The filter is attached to a custom made machined adapter into the standard Holley dual feed fuel line with a fitting for the guage. The smaller cylindrical fitting just the right of the gauge is the adapter and the larger cylindrical fitting is the fuel filter. I have since purchased a new dual fuel line and eliminated my custom adapter. Hope this helps. If you need anymore info let me know.

Looking at the picture of your motor, I have a question. You have the steel lines connnected to your carb, with the pressure gauge. Does it then connect directly to the fuel filter? I cannot zoom in enough to see.
