FYI, Holley is recalling several fuel pressure regulators manufactured in 2024 and 2025. If the diaphragm fails, fuel spews out everywhere. Apparently I got one before the recall came out. I only fired up my 347 with the Pro Flo today. After about 20 minute
s of run time, fuel was spraying everywhere. Scared the crap out of me. I can't imagine what idiot designed a fuel pressure regulator with a weep hole. Very dangerous. https://static.nhtsa.gov/odi/rcl/202...5E036-8756.pdf
