Product Details

The Fuelab 57503-1 is a precision-engineered 575 Series mini fuel pressure regulator designed specifically for carbureted applications. This compact blocking-style regulator delivers reliable fuel pressure control in a package that is 50 percent lighter than the standard 555 Series while maintaining the same precision performance.

Key Features:

  • Adjustable pressure range: 10-25 PSI for carbureted engines
  • Advanced poppet design with no-creep soft seat for smooth, consistent regulation
  • One -6AN inlet port and two -6AN outlet ports for flexible plumbing options
  • CNC-machined billet aluminum construction with Type II military-spec anodizing (MIL-A-8625)
  • Compatible with gasoline, diesel, methanol, and E85 fuels
  • 1/8" NPT gauge port with plug for external pressure gauge installation
  • 1/8" NPT breather vent for proper venting
  • Fine thread pitch adjustment screw for precise pressure tuning
  • Includes versatile mounting bracket with stainless steel hardware
  • Backed by Fuelab's limited lifetime warranty

The 575 Series represents true precision instrumentation for fuel system management. Its compact design makes it ideal for tight engine bay installations where space is limited, while the robust construction and fuel compatibility ensure reliable performance in demanding racing, off-road, and marine applications.

Autoplicity products are much cheaper than anywhere else. I was happy to find a good product for that price. Just waiting for the order to arrive.

Best price and easy to buy using my Amazon account

It was easy to order the item I needed.

Thank you for having goodmark products. Easy to use web page. I like the price and the fact you use paypal. Thank you.

Awesome deal

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Cheaper price than the competitors and free shipping. It's pure win.

First experience so we'll see. So far it has been easy.

great experience, great prices. Although, it would be nice to have a description listed of the part numbers i ordered.

Great seller! good communication between autoplicity and buyer!<br>Also very quick to process and send out product! Got order within 6 days standard shipping! Will purchase from again!!
