Fuel Regulator

I ordered the adapter from Clifford yesterday, and the guy on the phone said I need a fuel regulator to limit it to 2.5 lbs. This is being used with the 5200. I had not heard about this before - any insight?
 
yes the weber progressive carbs (32/36) are sensitive to fuel pressure. The 5200 is a Holley/Weber version of the 32/36 and needs the regulator.

My Weber was running rich so I bought some jets and a fuel regulator and my milage improved significantly. I don't recall if I ran a few tanks prior adding the fuel regulator. But with the jet changes and the regulator, I went from an average of 18.5 mpg to about 22.5 mpg. One trip I set the regulator lower and I had some tanks of highway driving at 25 mpg. But when I hit some mountain grades, I had a fuel starvation problem and had to bump it back up to about 3.5 psi.

Did a little more searching...Could I get something like this?

and pick up some brass fittings from my hardware store. I guess I would get 3/8" NPT with a barb on the other end, then use rubber fuel line hose and stick it on, near the carb? Let me know if that sounds good to you guys.

If there's a cheaper one, that'd be nice too :)
 
That's pretty much perfect.

I have a spectre fuel pressure gauge that I bought, used for about 5 minutes, and then realized it wouldn't work with my turbo setup.

I'll sell it to you for cheaper than that :)

Worked great while the turbo wasn't hooked up...
 
The spectre will be better for your applicatiojn anyway, as the holley is for 4.5-9 PSI and you need one for 2.5-3 PSI for the weber carb.The spectre is 1-5.5 I believe.
 
I have the summit branded version of the holley and it works great-a few bucks less as well. Without one the bowl will flood.
 
I was going to mention the same thing about the pressure range on the Holly regulator. The one you linked to is from 4.9 to 9 psi. There is one that goes from 1 to 4 psi.

As for that Spectre regulator...be careful. I had one from Crane that looked EXACTLY like the one from Spectre (does Crane make it for Spectre or vice-versa?). After about a year, I started the car in the garage one day to have the regulator start dumping gas out from under the dial where you adjust the psi.

Gas was pouring all over the running engine and header! :shock:

I didn't even know it happened till after I got out of the car and saw liquid running to the drain in the garage floor. At first I thought I blow a radiator hose till I looked at the engine and almost had a heart attack.

It looks like an internal diaphram went. Luckily, there was no fire but I now keep a fire extinguisher in the garage!
 
Regulator, huh? MPG being my main concern, I might want to try this. I have an inline electric fuel pump @ 7-9psi and running a Holley 1940 carb. I've been running it like this for nearly 5 years now. What do you think?

I don't figure it'll help unless the fuel pump is pushing past the seat, then out a vent hole or something but you never know.
