    Re: fuel return line restrictor

    Yes you use a main jet as a restrictor. You can either use a quick disconnect restrictor Part# QD-14 or an inline restrictor Part#RY12-RLR-14 For reference check out http://www.hotproductsusa.com/PDFs/2009/2009_Intake.pdf

    I like to use the quick disconnect style fuel restrictor and I also usually run a #60 main jet for a restrictor.

    Scroll down about 1/2 way.

    Depending on what size you need welding tips fit nice in the line. They come in a few different sizes.

    Raises the fuel pressure and reduces chances of a lean out condition.

    These things are awesome and the least costly that I've found.

    Never argue with an idiot, they will drag you down to their level then beat you with experience.

    Re: fuel return line restrictor

    I know this is an old thread but I was wondering if you can install one of the quick disconnects after you "Y" the return lines together, or would it be better to run individual regulators on each carb? Thank you for your help.
