Fuel Line T-Fitting Adapter for Fuel Pressure Gauge Sensor 1/2 3/8 Inch
Fuel Line T-Fitting Adapter for Fuel Pressure Gauge Sensor 1/2 3/8 Inch is the robust, corrosion‑resistant solution you need to monitor your engine’s fuel system directly from the source. Crafted from 304 stainless steel, this tee fits both 1/2" and 3/8" inner-diameter fuel hoses with a reliable quick‑connection design. The middle port is 1/8-27 NPT, ready to thread in standard fuel pressure gauge sensors, giving you precise readings where it matters most for tuning, diagnostics, and peak performance.
Designed for versatility, this universal-fit adapter works across cars, motorcycles, trucks, boats, and other vehicles. The barbed push‑lock ends ensure a secure seal, while included plastic rings and hose clamps help maintain a tight, leak‑free connection under high‑temperature operation. Keeping track of fuel pressure is essential for preventing lean or rich conditions, supporting faster diagnostics and more accurate adjustments during maintenance or performance upgrades.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
