A while ago I tried to put together a high flow fuel rail setup with the ATP fuel rail and failed because I overtightened the fittings at the end of the rail.
The original setup looked like this:

I ordered the replacement fittings but never got around to re-doing it... until now.
I found the original setup was too clunky (I made it up taking measurements with the stock fuel rail in place), so I re-designed it and did it right this time, taking measurements with the high flow rail on the car (I had to rebuild all my fuel lines, re-arrange the fittings, etc...).
Here is what the end of the fuel hard line looks like, pretty straightforward.

This is how I measured the fuel line length, I duct-taped the end of the braided line, marked it where it needed to be cut.

Getting there...

Testing time, as you can see, the setup holds the pressure just right (the actual fuel pressure should be 58psi but that gauge consistently reads 2 psi lower, I tested it's accuracy with the two other gauges on my boost leak kit).

To make a long story short, I had to take it off 2 more times, the ATP rail wasn't threaded deep enough and I sprung a leak at both ends. I re-threaded both ends so that I could screw the end fittings in completely.

Unfortunately, I screwed up 2 threads on one of my fittings, discovering that the rail wasn't threaded properly so I have a tiny little leak at one end of the rail.

Now the stock rail is back on (again) and I'll order another (or maybe five) rail end fitting to finish off this project.

 

can't you just plug one side of the rail like stock ones?

 

I do have the plug but I really wanted to do the 2 line thing.
