You can see the fitting here, right under the regulator and the 90 degree bend off the bottom (return).

The elbow and throttle body fit under a stock SS hood. (fits right up into the scoop cowl area)
However, after the throttle body i have a 4 inch tube feeding to the stock black 1le elbow. Since i changed the angle that the elbow was sitting at, it wouldnt clear and I had to make about a 4 x 6 inch knotch in the underside of the hood. After that was done, all fit great.

Thanks!
Thanks!
The Pure Choice fittings just snap on to the rail like the original lines do & have a -6 Male fitting on the other end... I can email you a pic of them if ya need it.

Re: What size fuel line is the feed and return on LT1 rail?
I'm going to go with the purechoice fuel rail fittings for the return line and i did some welding of an 3/8 npt to -8an male fitting to the feed of my fuel rail on a machine shop.
This way i keep the regulator in the stock location, since the dual in tank pumps only jump in with boost, well.... no need for bigger return lines... i will just re route the fuel lines through where i want them to go...
