    Rated 5 out of 5 by from High Quality! This regulator may be inexpensive, but it is definitely not cheap. The whole assembly is solid and well constructed. Adjustments are very easy to make if the preset pressure is not preferred, and the pressure is maintained accurately regardless of temperature. Be sure to attach the mounting bracket to the regulator before attaching the inlet fuel line!
