Which fuel pressure regulator?
 

I was just wondering if it made a difference what fuel pressure regulator I used on a Holley 600cfm? I was looking at a Holley Two Port 4.5 - 9 PSI. 3/8" NPT ports
.220" (7/32") restriction. Which would be the best? I want one with a guage mounted on the side but I don't know which is best? Please help me out!
Would this one be alright? http://cgi.ebay.com/ebaymotors/FUEL-...QQcmdZViewItem

Don't buy that cheap eBay crap, shipping is 20 bucks, that's nuts. I can buy a Holley 4-1/2-9 psi fpr local for 25 and a cheap gauge for another 11, add 10-15 bucks in brass fittings and I have all the parts needed to install other than fuel hose and clamps.

I bought the holley blue kit which has the pump and fpr worked really good. I went with an in line fpg. I would like a bigger 1 to mount to the cowl but I dont know.
