Description
The OneFastShop 7.89mm Dual Quick Connect Fuel Fitting is a precision-engineered solution for splitting fuel lines directly from any 39mm fuel pump outlet, including popular models such as the Walbro 450, 525, and 535.
This fitting provides dual 7.89mm quick-connect ports from a single pump outlet, eliminating the need for adapters, hose clamps, or external Y-blocks. Ideal for high-performance and high-volume fuel systems, it supports dual-feed, return-style, and other custom configurations.
Constructed from CNC-machined 6061 aluminum with a black anodized finish, this fitting offers strength, precision, and long-term resistance to corrosion. The included Viton O-ring and locking clip ensure a secure, leak-free connection even under high fuel pressure.
Compatible with all fuels, including ethanol (E85), this fitting is fully reusable and requires no permanent pump modification, making it a versatile solution for performance builds.
