GlowShift Fuel Line T-Fitting Adapter for 1/2" I.D. Hose — 1/8-27 NPT Port, 304 Stainless Steel with Hose Clamps

The GlowShift 1/2” I.D. Fuel Line Barbed Push-Lock T-Fitting Adapter lets you add a fuel pressure sensor to a 1/2" inner-diameter fuel line quickly and securely.

This compact stainless-steel T-fitting is purpose-built for vehicles and custom fuel systems that use 1/2" (12.7 mm) inner-diameter hose. It provides a threaded 1/8-27 NPT port to accept standard fuel pressure sensors or gauges while using barbed push-lock connections and included hose clamps for a leak-resistant install. Made from corrosion-resistant 304 stainless steel, the adapter is designed to withstand fuel exposure and repeated service, and it ships with step-by-step installation instructions.

How does this T-fitting let me read fuel pressure on a 1/2" fuel line?

The T-fitting replaces a short section of 1/2" I.D. fuel hose to create a branch with a sensor port. The barbed ends mate to the hose while the 1/8-27 NPT threaded port accepts most fuel pressure sensors or adapters used in aftermarket gauges.

• 1/2" (12.7 mm) barbed push-lock fittings for standard hose connection
• 1/8-27 NPT threaded port compatible with common pressure sensors
• Comes with two hose clamps to secure connections

What materials and durability features protect it from fuel and corrosion?

The adapter is machined from 304 stainless steel, a commonly used grade for resistance to rust and many fuels. That construction reduces the chance of contamination, pitting, or failure from normal exposure to gasoline, diesel, or ethanol-blended fuels used in most applications.

• 304 stainless steel body resists corrosion and fuel degradation
• Barbed fittings designed for tight push-lock hose fitment
• Supplied hose clamps add mechanical security against leaks

How easy is installation and what’s included in the box?

GlowShift includes step-by-step installation instructions to simplify the process, so most mechanically inclined users can install the fitting with basic hand tools. The kit is compact and uses common thread and hose sizes, minimizing the need for additional adapters.

• Step-by-step printed instructions included
• Two hose clamps for securing the 1/2" I.D. hose to the barbs
• No special fittings required beyond the sensor (1/8-27 NPT)

Will this work with my gauge or sensor—what should I check first?

Confirm your sensor or gauge accepts a 1/8-27 NPT thread, and verify the vehicle’s fuel hose inner diameter is 1/2" (12.7 mm). If both match, the GlowShift T-fitting will provide a direct, compatible connection point for fuel pressure monitoring.

• Sensor thread must be 1/8-27 NPT for direct fit
• Fuel hose inner diameter must be 1/2" (12.7 mm)
• Use included clamps and check for leaks after first start-up

Who is this for: The GlowShift 1/2" I.D. Fuel Line Barbed T-Fitting Adapter is aimed at enthusiasts, DIY mechanics, and professional installers who need a reliable, corrosion-resistant way to add a fuel pressure sensor to a 1/2" hose. It’s ideal for performance builds, diagnostics, or maintenance where accurate fuel pressure readings are required, and for anyone seeking a compact solution that uses standard sensor threads and common hose sizes. GlowShift stands behind the product with a one-year limited warranty, free lifetime technical support, and a 30-day return policy should you need assistance or a replacement.
