I am upgrading the fuel system on my cobra engine and i am planning on sticking with a returnless system till I can afford to upgrade completely to a return style system. I drew up the below set up that I think is the correct way to go about this for now but I wanted to get a second opinion before I go ahead with this. What do you think?



On a side note I have MMR fuel rails that I am using and will be using all braided lines

That should work fine, but it is more over designed than necessary for reasonable hp. You can get 600 rwhp (pd blower) out of the stock 1/4" line and stock rails. Beyond that you can add another 1/4 line to the driver side rail and be good to 750 rwhp. All this assumes that you have a fuel setup that will produce sufficient pressure and flow.

Well i was starting from scratch for the fuel set-up on the engine so I thought I would make sure I only have to do it once. Plus I got an excellent deal for the rails brand new.

Thats overkill on your drawing.

You only need your fuel supply line coming into the back of the passeger side rail, a cross over from the front of the passenger side to the front of the driver side, and then plug the back of the driver side rail.
