    Excellent communication from the seller. Super fast delivery, arrived the very next day! Excellent Holley fuel pressure regulator that actually works perfectly! not like the pro-comp speed master ones that don't regulate.

    Solved my probem!

    I recently rebuilt a '74 Corvette that was fitted with an LT-1 engine. I had the Holley carb professionally rebuilt. Initially everything was fine but I randomly started having what seemed like carb problems. Gas smell in garage after being parked, running rich, plugs wet & dark when I pulled them. I tried changing fuel inlet seats, jets & tightening carb bolts up and it was still intermittent. Then after reading an article on how critical fuel pressure was I checked mine and it was 9# at Idle ... supposed to be 6#. With this fuel pressure regulator it was 6# out of the box and so far no more issues with all original parts put back in carb. The instructions in the box were a little confusing as they're for Holley Electric fuel pumps that reference this unit but I'm very pleased with it.

    Title is fine.

    It works and looks good. Although they should have included mounting instructions. The mounting holes were not threaded and the mounting screws had to be forced threaded into the holes. This I did not realize this at first, and thought that they forgot to thread the holes. I would think that on a part like this, the holes should be factory threaded unless there there is a reason for not doing so.

    Nice for the price

    it looked great right out of the box. It does not come with connectors (does not say it does either) so I had to purchase hose connectors. one output leaked when tightened so I had to use teflon tape to seal it (instructions say not to use tape). it is advertised to be 6.5 pounds preset, mine was reading a little higher so I had to adjust it (which is easy to do).

    Soes what it is supposed to do.

    Hold pressure at 5psi as needed. Some installation issues: had to tap the mounting holes, one mounting screw wrung off in the firewall (cheap screws) and the lock nut for the adjusting screw is some weird size (had to finally use an adjustable wrench). But, like the title says, once installed, it worked perfectly.
