    Fuel line routing for 600+rwhp EFI

    Are most of you running Y-block before the rails or are you just running the feed line to one, the other rail, then to the regulator?

    The Y-block seems like the right thing to do but I just wonder how necessary it is.

    MMR told me to run a Y-block before the rail so your feeding each rail.. then both out of the rail into the Regulator then your return back... Thats how mine is getting setup..

    It is probably a smart thing to do.

    I run mine like Blownby and haven't had any problems. The Y block seems like a better setup, but more of a pain to plumb. I was thinking about changing mine since I am about at the limit of my SX pump.

    I have a y ill be putting in my setup. Trying to figure out what to run though. I thought 10 to the y, 8's to the rails, 6's out of rails to regulator and 8 from the regulator to the tank. Does this seem right?

    Yeah I still don't think I need the Y though. I think I'll see if I can get by without it. the tiny stock lines feed in this way - one rail at a time and you can go along way with that. I think i'll take my chances. To run the Y block cost about $120 more dollars the way i figure it.
