Holley HP Billet Fuel Pressure Regulators

Part of Holley's complete line of fuel system products, Holley HP billet fuel pressure regulators are available in a variety of configurations for carbureted or fuel injected engines. Some versions are even adaptable to either carburetors or EFI. They allow you to upgrade a carbureted system to EFI without replacing the fuel pressure regulator.

All HP billet fuel pressure regulators feature a 2-port design, provide for precise fuel pressure adjustments, and are available in your choice of demand (no return line) or by-pass (with a return line) styles. Depending on the model, they are for use only with electric fuel pumps, or with either mechanical or electric pumps. Designed for street/strip applications, they are CNC-machined from 6061 T-6 billet aluminum for strength and have bright dip anodized black bodies with clear dip anodized tops for corrosion resistance and good looks. Whatever your fuel system needs, Holley has you covered.

Depending on model, features may include:

* Adjustable from 4 to 65 psi for use with EFI or carburetors
* 4.5 to 9 psi adjustment range for use with carburetors only
* EFI-only models are adjustable from 15 to 65 psi
* Two port sizes available, 3/8 in. NPT or -6 AN inlet/outlet and return (where applicable)
* Fitting for manifold reference
* 1/8 in. NPT gauge port
* Boost reference--1:1

Amazing!
Color: Cyano Pink Spicule
This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.

Brightens, doesn't firm
Color: Cyano Pink Spicule
I've been using this for about a month now, every night on my face and neck, hoping to reduce the appearance of wrinkles and tighten some of my skin in that area that seems to be losing elasticity. On my neck, I've honestly noticed no real difference in 4 weeks of continued, consistent daily use. The skin on my face does seem brighter and somewhat less textured than before, but I haven't noticed any change in the issues I was hoping this would resolve, based on the claims and how it was marketed. So... not a bad addition to my skincare, but not the solution I was looking for. Some have expressed concerns about it tingling or stinging... You can feel something when you apply it, it's almost like the feeling of static electricity, but it's very mild. I wouldn't let that stop you from giving it a try if you were concerned about it. It didn't cause my sensitive skin any breakouts or redness (although I was applying it at night before bed, so perhaps any redness was calmed overnight). I'm going to go ahead and finish the bottle, but based on these results, I probably won't repurchase.

Great quality!
Style: Dual Dash Cam Without Card
I’m really impressed with this dash cam! The video quality is super clear both during the day and at night — you can see details perfectly. The dual camera captures both the road and the inside of the car, which gives me extra peace of mind. Setup was very easy, and the screen is bright and easy to navigate. The wide-angle lens covers a lot of area, and the loop recording and G-sensor features work flawlessly. Great value for the price — definitely recommend this one!
