mallory 4309 FPR?
I just picked up a new 4309 FPR but it did not come with any instructions. Can someone please tell me which ports are in and out and which one for the return. I will be using a Weber carb.
Thanks, Ed

I have the 4309 hooked up to the stock feed & return line with a summit 0-15psi guage at start-up it will read like 5.5psi but after running her around the block a few times it will go down to 3.5psi is this normal? Or do I need a larger return line. (carbs are RE dual 36dcd's and psi readings are at idle....

your return line is fine, leave it alone

Thanks guys!
Robert I'm going to run the motor NA first until I get it broken in. Do I just leave the vac port open until I add the snail?
Thanks, Ed

you can run it either way, it will work fine

I dont have the reference port hooked up yet as I am not turbocharged just yet but will be soon which is why I purchased this particular regulator. So even still... It is normal for the pressure to settle down after the car warms up?

I think this is more of a gauge issue rather than the fpr. I had the same problem on mine. I ran both the Holley fpr and now the Mallory 4309, with the same gauge. The gauge drops off after the engine has run for a while. Shutting it off and restarting will usually bring the reading back up, only to watch it drop again after running for a bit.
