which fuel preassure regulator

I will be running a 2300 series Holley carb and I bought the 12927 Holley TBI fuel pump. Summit says it pumps 15 PSI max, but Advance Auto's book had a flow chart that showed it flowing over 30 GPH at 25 PSI, and Holley's website dosn't say the max. anyway, I only have to pump 17 PSI anyway, which it should stay over 35 GPH ( only need 33 at full boost ). I bought it at advance auto. but which regulator should I run, I know there is a good aeromotive reg with the boost refrencing, but I don't know which 1 it is, there's several aeromotive reg's in summits book, and I don't need somthing with 4 outlets, so I know that's not it...
 
I am using this one

it is a 4 port but I just put plugs in the other ports. it also includes a spring you can put in it for EFI pressure ranges. I bought it at my local speed shop new for $99 though. the included bracket is more for a V8 but I hung it off the backside of the carb mounting stud. also the way you install them is running your pump line to one of the "4 ports" and the carb line to another. the return comes out the bottom of it and that goes back to your tank.

I went with it since I knew I would be going EFI later on and this could go both ways if needed. plus it looks pimp. my shop had no black fittings in stock though....might order up some so it looks nicer instead of the blue ones I have right now.

for a pump block off you can use a chevy one. I think it is for a big block though? (should have two holes and not 4) the bolt holes will be 3/8" though so you will need different bolts. also they installed one on the early factory 2.3L motors that was plain steel. ford motorsport also makes a nice chrome one you could use.
 
oh yeah. you can use one of the other 4 ports for a gauge to be mounted in (using a reducer bushing) so that is 4 of the ports you will use to install it. the 4th could be used for nitrous fuel supply.
 
the aeromotive fpr is great.... I use the same one on a 4.3 chevy tbi turbo.
 
well, I'm going to order that regulator. I picked up the F/P today, opened the box, pulled it out and noticed it was really a Waleboro pump, so I ran the Waleboro part # thru there site and found a flow chart, in which it should do over 40 GPH @ 40 psi ( at 13.5v ), so Holley's ratings are under rating the pumps capabilities.

Walbro Makes all of holley's (and a lot of other companies) Pumps.

They are high quality.

I kno, I'm not complaining. it's actully the pump you may want to buy for your holley Projection TBI. it's the same pump that comes in the newer Projection TBI's, and is sold individually by Holley as a replacement.

I have the Walbro 392, not installed, yet awaiting more parts to come in. Yes that one should do the trick, and I also have the Aeromotive 13301 FPR.
