The Fuelab 51506-1-L-T is a 515 Series adjustable fuel pressure regulator engineered for TBI (throttle body injection) applications with a large seat design. Built for performance and versatility, this regulator accepts both port-style and non-port-style union fittings without interference, making installation flexible across various fuel system configurations.

Key Features:

  • Two -6AN inlet ports and one -6AN return port (bottom-mounted) for clean routing
  • Adjustable pressure range suitable for TBI applications
  • Compatible with gasoline, diesel, methanol, and ethanol fuels
  • Precision-machined billet aluminum construction with Type II anodizing per MIL-A-8625
  • Fine thread pitch adjustment mechanism for precise pressure tuning
  • 1/8 NPT gauge port with plug for external pressure monitoring
  • 1/8 NPT pressure reference port with barbed fitting included
  • Versatile mounting bracket with stainless steel hardware
  • Backed by Fuelab's 2-year limited warranty

The 515 Series regulators support a wide range of applications from carbureted systems as low as 1 PSID to fuel-injected systems up to 125 PSID. The large seat configuration in this model is optimized for higher flow demands typical of TBI setups, ensuring consistent fuel delivery and stable pressure regulation.

Fast shipping, good customer service!

Autoplicity agent was very helpful over the phone. He answered all my questions & even did some research to make me feel comfortable I was getting the appropriate parts I needed for my car. I was very pleased & will shop Autoplicity again.

Everything went smoothly, love the prices and the ease of transaction, hope to buy from you real soon, Nice people.

I RECEIVED GREAT SERVICE WITH AUTOPLICITY. THERE WAS AN ITEM ON THEIR WEBSITE THAT SAID OUT OF STOCK SO I CALLED AND ASKED WHEN THEY WOULD BE GETTING MORE AND THEY GUY WAS VERY POLITE AND HELPFULL. NOT TOO MENTION THE PRICE WAS WAY BELOW THEIR COMPETITORS. I WOULD RECOMMENT AUTOPLICITY TO ANYONE AND I WILL CONTINUE TO DO BUSINESS WITH THEM.

Great shopping experience except I did not receive the discount promised by the web site because I could not find any place to enter the coupon code during check out. Otherwise I'm glad to find your site. One other small issue. I did not receive any trac

Best price on the net! Haven't got my order yet, it just shipped so we will see from there.
