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

Wide toe box
The color is pretty on these water shoes. The toe box on these shoes is wide which collects water making it difficult to use them walking for exercise in the water. I bought these specifically to keep my feet protected. The sole is the perfect thickness needed but can’t use them for what they were bought for.

Good and affordable
Size: 6-7 Women/5-6 Men, Color: 1a-stripe Black-2
Pretty good and effective for the price! I wore these to volcano bay in Orlando and they got the job done. While these water shoes have great comfort, traction, versatility, and water resistance, they don’t have a lot of support on the sides of the shoe. They also are tight/snug around the ankles. Theyre very lightweight and can bend and fit in a fanny pack or purse, but if you’re looking for a supportive water shoe, these aren’t it. But if you need something to just get the job done so you can have fun, these are it!

Solid and comfy
Size: Medium, Color: Black (001)/Jet Gray
Absolutely love these sports bras. They’re simple and solid, and I love the colors! They do run small, so I’m glad I sized up. I’m usually a small, but got a medium and they fit perfectly. For reference I’m 5’5”, 125lbs, 34B. They wash well too! Just make sure to air dry them and wash on cold only.

Great bra, poor customer service
Size: Medium, Color: Black (001)/Jet Gray
I like this bra. It offers great support. But the sizes run small. I remembered this after placing my order. So I got back with Amazon two times within six hours of placing the order to cancel, so I could exchange it for a larger size. Amazon would not cancel the order. And they have no option for exchanging it. They used to allow 24 hours before processing an order. Not so here.
