With your Novarossi motor, the pressure chamber will not do much to improve milage. The NS motors require a little more fuel tubeing. I get 5 min 30 sec with mine. The best thing I did was go to the Novarossi power 12 SCT. I can get over 6 min with mine. Just add a little more fuel tubing for the NS.
use the pressure vessel as a big ass fuel container! I don't use them on my small blocks only big blocks.

here's another new pressure regulator and exhaust gas coolant, whats nice about this one is check out the check valve on it, I haven't seen that on any of the other ones....[URL="http://rbmods.net/rbshop/index.php?target=products&product_id=151"]
