Product Details

The Big End Performance 12140 is a precision-machined fuel system adapter fitting designed to connect -6AN hose ends to 14mm x 1.5 metric threads with O-ring sealing. This blue anodized aluminum fitting provides a reliable, leak-free connection for fuel systems, power steering applications, and other hydraulic plumbing needs.

Key Features:

  • -6AN male flare connection with 37-degree sealing angle
  • 14mm x 1.5 metric thread with O-ring seal design
  • Premium aluminum construction with blue anodized finish
  • High-pressure rated for demanding fuel system applications
  • Commonly used for GM TBI conversions, LS swaps, and modern EFI systems
  • Compatible with gasoline, alcohol, and methanol fuels

This adapter fitting is ideal for connecting AN-style fuel lines to factory fuel rails, fuel pressure regulators, or power steering components that use the 14mm x 1.5 O-ring port. The O-ring seal design ensures positive sealing under high pressure, making it perfect for performance fuel system upgrades and engine swaps where AN fittings are being integrated with metric threaded components.

Lowest price on the INTERNET!!! I searched for days and nobody could even come close to their price. They provided excellent feedback on my order status including shipping and tracking numbers.

Very nice site easy to use and fast checkout

OUTSTANDING ALL THE WAY ARROUND. Super prices (2/3 of the price of your lowest competitor). Shipping cost was 25% of what others wanted. Recieved 5 days from order date. I will shop here again and will recomend to others.

I just received my order, I was expecting it on Saturday so that was a nice surprise. I will have to install it in my car and then finish my comments. Then I will let you know the rest of the story. Thank you.
