Another + for Ben. Good dude, and i'm sold on Coldfire. I'm with Bruce too though. 20# in our cars is stoooopid. I have it to be legal. Never have set them off. carefully actuator placement is worth it.

Two common ways to set up, FC way is one actuator sets off 20# of mess. The other way is how mine is. Two actuators, one for each bottle. Each bottle is aimed at head gasket area of motor, and my twig & berries.
