Overall Assessment

Customers appreciate the quality and aesthetics of our regulator housing, often favoring it over competitor brands like Holley. While some were initially met with a diaphragm leak, the issue was easily resolved with a supplement repair kit. The product’s adaptability and functionality are noted, particularly for use with cam-driven Hillborn pumps, making it a cost-effective solution. The product's ease of adjusting pressure was praised. Some customers reported issues with regulation and leaks, suggesting room for improvement in our instructions and components. However, overall, the product’s practicality and usability still stand out.

Regulator housing is beautiful, diaphragm leaked immediately. Bought Holley rebuild kit for 9 bucks now it works perfectly. If you buy one get rebuild kit. Still for 30 bucks not bad and better looking than Holley regulator

Would Recommend

Loved it. Would absolutely buy this product again!!

OK, I have a dragster that will eventually have a blower with an 8 hole Crower fuel injector. To start, I plan to run a Holley carb with no blower....just to get used to driving this beast. Rather than buying another fuel pump, this regulator was used with a cam driven Hillborn pump to help bypass fuel back to the tank. It is doing its job perfectly. It was a great temporary solution without having to buy another pump. Thank you Speedway!

Would Recommend

Definitely buy again and always at Speedway Motors

No instructions with the unit. The bottom fitting is the inlet, the side fittings are outlets. I made my own bracket, spent $15 on brass fittings, and modified my inlet lines. Turn on the electric fuel pump, and this regulator starts leaking. A lot. And the pressure goes right where it was (12 pounds) before I installed it. Took it off, took it apart numerous times, experimented with the adjustment. (Screw the adjusting screw out to lower the pressure, or at least that's how it's supposed to work.) With it assembled, no matter what I do, the ball will not seat well enough to slow the flow. And it still leaks.
