According to the rule book... It should be fine as long as the lines are steel braided.

you should mount it in front of the engine. i dont know how fast you go but it is less accurate on the side of the engine or behind it. gravity is your enemy so mount it at least in front of the engine or off to the side but in front.

i learned that expensive lesson with the nos. never could figure out why the engine was always lean. look at all the heavy hitters. all their regulators are in front of the carb and intake. i never had that problem until i started running in the low 9's and high 8's.

NHRA rulebook states that fuel regulators cannot be mounted on the firewall.

Yeah, scratch that...

A fuel pressure isolator is the only thing they allow on the firewall. Anything else needs to be 6" ahead of the flywheel.

Yeah, mounting it to the firewall is not legal. We just mounted ours to the inner fender....

Even the isolator according to the instructions from auto meter cannot be mounted to the fire wall ????? per nhra/ihra. I haven't checked the rule book but this is what is stated in the instructions.Any one ever had the isolator questioned at tech??? I've had one on the firewall for the last 5 yrs. ?????
