0-100 PSI Range:

The 0-100 PSI range covers most fuel system applications, from naturally aspirated engines (typically 40-60 PSI) to high-boost turbocharged builds (60-80+ PSI). The wide range ensures accurate readings across all operating conditions, from idle to wide-open throttle. The gauge provides clear, easy-to-read markings throughout the entire range.

Mechanical Operation:

Mechanical fuel pressure gauges use a bourdon tube mechanism that responds directly to fuel pressure - no electrical connection is required. This mechanical operation provides several advantages: no wiring needed, no power consumption, instant response to pressure changes, and reliable operation in harsh environments. Mechanical gauges are ideal for both permanent installations and temporary diagnostic use.

1/8" NPT Fitting:

The 1/8" NPT (National Pipe Thread) fitting is the universal standard for fuel pressure gauge ports. Most fuel pressure regulators, fuel rails, and fuel system components include a 1/8" NPT port specifically for gauge installation. The NPT thread design creates a seal as the threads tighten, providing a leak-free connection when properly installed with thread sealant.

1.5" Compact Size:

The 1.5" diameter makes this gauge compact enough to fit in tight engine bays while still being large enough to read easily. The compact size is ideal for mounting on fuel pressure regulators, fuel rails, or in small gauge pods. Despite the small size, the blue face and white markings provide excellent visibility and readability.

Glycerin-Filled:

The gauge is glycerin-filled to dampen vibrations and provide stable, easy-to-read pressure readings. The glycerin fluid inside the gauge absorbs vibrations from the engine and fuel system, preventing the needle from bouncing and making it easier to read accurate pressure values. Glycerin-filled gauges are essential for automotive applications where vibration is constant.

Blue Face with Brushed Housing:

The distinctive blue face with white markings provides excellent contrast for easy reading in all lighting conditions. The brushed aluminum housing delivers a premium, professional appearance that complements any engine bay or gauge cluster. The blue face is a signature DeatschWerks styling element that stands out from standard black-face gauges.
