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.

thanks alot for the replys i was also told to use a #60. if its not to much to ask why the restrictor does the fuel actualy run thru that fast does it create a differant pressure on the pump or pop off pressure anyway thanks again this is a great site w/ a lot of good fun people

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

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