What should fuel pressure be?

[fathead]

I have a 22r w/ dual webers in my 4 seater. What should the fuel pressure be set at?

[clogking]

Webers need a max of 3 lbs Fuel pressure. Thats all !!

That's what I thought I had heard, next question, and hopefully not a dumb one. I have a gauge on the pressure regulator, is this a set it at idle and forget it type thing, or do I need to set it at a certain RPM?

Unless it has a vacuum hose going to it, set at idle and forget it.

There are no dumb questions. Do you use a Electric fuel pump? If so then makes no difference but i would check the mechanical fuel pump at say 2000 RPM just to be safe. And how is Syncing the carbs going?:eek:

Syncing the carbs? What do you mean? Just kidding, I think they are pretty close, if not spot on ( if that is ever possible!!)
The motor runs great, I get a little bit of flooding when I go through a long whoop section, but it is usually for the better, as it is just a beam car and the flooding keeps me from getting in trouble!
Also, yes, it is an electric pump.
Thanks for all the help guys...

Lowering the upper float level 1/16" can go a long way in preventing flooding. Another trick, which is easier, is to lower the fuel pressure 1/2 to 1 lb. As long as you don't notice it flattening out when wide open running its okay. The 3 lbs. is the max. pressure allowed without damaging the needle seat. If your pump has plenty of volume, a lower pressure is often better and will increase your gas mileage.
