Fuel pressure regulator where to mount

As close to the carb as possible.

Most guys bolt them on the fender, and NHRA regs says it must be 6 inches from the firewall, but the closer to the carb the better.

I had all these questions myself and I 've been wondering why none of the fuel issues are mentioned in the Mopar performance chassis manual????

I guess they did not want to be held liable if someone had a fire and blamed it on the M/P advice, plus the rules and regulations change so frequently, they must have figured they better just stay away from that topic...dunno.
