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!

Just what it should be.

I've got a mean 1938 Chevy that was put together about 45 years ago. The electric fuel pump went bad a while back and I replaced it with a Jeg's pump which had too much pressure for the 800 Holley double-pumper. I wanted to keep the car as close as possible to the original look and build and didn't want a regulator and gauge showing. The Holley regulator said it was preset so I mounted it under the car on the frame and didn't use a gauge. The pressure setting from the factory works fine and I didn't have to stick a gauge anywhere,

works great

I have been using this for a couple months now, ( 69 pontiac 400 ) All seems to be good, no leaks, adjustable, pretty much all you need. Good overall. Chad.
