Getting close to starting my 300 build that has a Webber dual setup on it. I'm running a Holley red electric fuel pump with the regulator supplied. I would like some info on how to setup the regulator for initial start up. What pressure and where to install a pressure gauge and what not. Also what adjustments need to be made to the carbs.
Thanks, John

 

I hear the Weber carbs don't like much above 4 psi so the regulator with the gauge on the outlet has to be before the carbs.
Because you have to run 2 fuel lines I think they make a block "Y" with a port you can install a gauge so you can tell what the PSI is at that point.


DO NOT mount the fuel PSI gauge inside the truck! They make isolators to mount the fuel side in the engine bay and just run the gauge and the hose from the isolator inside.


As for the 2 carbs cant help much but I know they both have to pull the same amount of air. Just did a quick Google search and came up with this.
