Stimmel1647545512 Posted September 9, 2009 Report Share Posted September 9, 2009 almost positive its for running an aux fuel line like if you have a pump for each rail you can put it in there Quote Link to comment Share on other sites More sharing options...

BDHG940 Posted September 9, 2009 Author Report Share Posted September 9, 2009 Its ported on both ends of the rails so it really woudnt make sense. I could be wrong but I dont think that is the case Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted September 9, 2009 Report Share Posted September 9, 2009 Its ported on both ends of the rails so it really woudnt make sense. I could be wrong but I dont think that is the case look closer..the end is right on the dizzy...so you have to use the one in the middle for the return. but this will vary with intakes. http://i5.photobucket.com/albums/y196/gearhead559/Shop%20stuff/100_3586.jpg i am not happy with the plumbing job on this one(i didnt do it) so i will be redoing it. but the basic idea is there for the correct feed and return. im going to feed from the rear, and return off the front, if not one side like most do.

schmuckingham Posted September 9, 2009 Report Share Posted September 9, 2009 Like Rob said its for the 302 width motors with a full size dizzy cap. Rail points right to the back of the dizzy cap and cant get a fitting in their so they use that hole. Only way to not use it is a 351 width motor or a small cap setup.
