Product Details

The Fuelab 57503-4 is a compact, high-precision fuel pressure regulator from the 575 Series, designed specifically for carbureted applications requiring 10-25 PSI fuel pressure. This mini regulator features a blocking style configuration with one -6AN inlet port and two -6AN outlet ports, making it ideal for high-performance carbureted engines where space is at a premium.

Key Features:

  • Advanced poppet design delivers smooth, consistent fuel pressure regulation with no-creep soft seat technology
  • Precision-machined from billet aluminum with military-spec Type II anodized finish for maximum durability and corrosion resistance
  • Compatible with gasoline, diesel, methanol, and ethanol fuels including E85
  • Fine thread pitch adjustment screw allows precise fuel pressure tuning
  • 1/8" NPT gauge port with plug for external pressure gauge installation
  • Includes versatile mounting bracket with stainless steel hardware
  • Compact mini design is 50% lighter than standard 555 Series regulators

This blocking-style regulator is engineered for carbureted racing and performance applications, offering precise fuel pressure control in a lightweight, compact package. The pressure range of 10-25 PSI makes it perfectly suited for carburetor bowl pressure management. Backed by Fuelab's limited lifetime warranty.

super easy to navigate through site... found what i was looking for ..... free shipping

So far so good.

Excellent deal!!! I was not able to find a better price anywhere. Fast shipping & just what I wanted.

good price!

Right item, right price !

Easy to find the part needed. Hope the remainder of the order, shipment, and delivery goes just as smoothly.

I would definitely order my auto parts from your shop again. I was impressed with the prices and the correspondence. Thanks!

I had a coupon code for 2% off my total order, but the site wouldn't take it.

great

they had the lowest price around for my car's k&n air filter. A great product at wholesale prices!

I had to find a fuel filter for my volvo diesel engine for my sailboat. It is not easy to find. I went to a number of boating and auto stores and could not find one. Fortunately, I was able to find one on this website. It was easy to search and easy to place the order. The next time I need a part this will be the first place I search. Thanks

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.

The whole process was some and quick. They also had the lowest prices available. Will be using them more often for sure!!
