Radium Engineering Fuel Pressure Gauge

Fits Most Models with 90 Degree Adapter

20-0407

Overview:

The Radium Engineering Fuel Pressure Gauge is a precision instrument designed for accurate fuel pressure monitoring across a wide range of fueling applications. Whether you're a performance enthusiast tuning your vehicle or a professional technician ensuring optimal fuel delivery, this gauge provides reliable readings with minimal needle vibration for ease of use.

Built to withstand demanding environments, it features a rugged stainless steel case and a clear acrylic lens, making it suitable for daily driving, track use, or custom fuel system setups. The black face and bezel offer a sleek, professional appearance that integrates well into most engine bays or gauge pods.

Key Features:

This fuel pressure gauge combines durable construction with precise functionality to deliver dependable performance:

• Accurate pressure range from 0 to 100 psi (0 to 6.9 BAR) with ±2% accuracy for precise fuel system monitoring.
• Silicone-filled dial fluid stabilizes the needle, preventing vibration and ensuring easy-to-read measurements.
• Clear acrylic lens provides excellent visibility while protecting the gauge face from debris and damage.
• Rugged stainless steel case measuring 1-5/8" outer diameter with a 1-3/4" bezel for durability and a clean look.
• Nickel-plated male 1/8" NPT fitting ensures corrosion resistance and secure connection to fuel lines or adapters.
• Includes a 90-degree adapter for versatile mounting options in tight or custom installations.
• Black bezel and housing provide a professional, low-profile aesthetic suitable for most vehicle interiors.
• Internal silicone bubble is normal and does not affect gauge performance or accuracy.

Construction & Design:

The gauge’s stainless steel housing offers robust protection against harsh engine bay conditions, while the acrylic lens resists scratches and impacts. The silicone-filled dial fluid not only dampens needle movement but also helps maintain consistent readings even under vibration or rough driving conditions. The nickel-plated NPT fitting provides a reliable, leak-resistant connection point compatible with most fuel systems.

The 90-degree adapter enhances installation flexibility, allowing the gauge to fit in confined spaces without compromising readability or accessibility.

Installation & Fitment:

This fuel pressure gauge is designed to fit most vehicle models with compatible 1/8" NPT fuel system ports. It is ideal for custom fuel setups, aftermarket fuel rails, or OEM fuel lines equipped with the appropriate fittings.

Installation requires the use of PTFE thread sealant paste on the NPT threads to ensure a proper seal and prevent leaks. Overpressurizing the gauge beyond its 100 psi limit can permanently misalign the needle, so care should be taken to operate within specified pressure ranges.

• Fits most models with 1/8" NPT fuel system ports.
• Use PTFE thread sealant paste on all NPT threads during installation.
• No cutting, drilling, or special tuning is required for proper installation.
