    return fuel rail to returnless?

    ok as some of you know im building a 6.0 and doing l92 heads/intake, i got the l92 intake and was looking at it and making sure everything was good on it since i bought it off ebay and noticed it has a returnless style rail, what will i need to do to run it in my truk since i have the return line on my fuel rail?

    plug the rail and run a vette filter?
    run a regulator before the rail that has a return line?

    let me know your ideas...thanks!

    All the info for parts to hook it up is in the obs conversion topic. The filter is a wix 33737 I believe.

    return line and pressure line both get hooked into the vette filter.

    your better off keeping the return style system. just use your rail on the intake
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    just take your old return style rails and have the cut and replaced with a -6an nitrous line. have it tig welded in place and your set make sure that the line your using is at least 12". once this is done you'll have no problems clearing the wider intake. i can take pics if you like
