Boltigen Fuel Pressure Gauge Inline 0-15 psi | 1/8 NPT, 3/8 Barb, Glycerin-Filled, Stainless Steel

Meet the Boltigen Fuel Pressure Gauge Inline — a compact, rugged tool designed to help you monitor fuel pressure quickly and accurately. With a glycerin-filled sensor and a stainless steel body, it delivers steady readings within a 0-15 psi range and stands up to demanding environments. The center back mount keeps the display in view, so you can check pressure at a glance while the system runs.

Key features at a glance

• Pressure range: 0-15 psi with glycerin-filled internals for stable, flutter-free readings.
• Connection: 1/8'' NPT threads for versatile installation in common fuel ports.
• Barb adapter: Includes a 3/8'' fuel line barb for compatible hose connections.
• Durable build: Stainless steel construction resists corrosion across fuel systems.
• Mounting: Center back mount offers clear visibility while the system runs.

Real-world uses and benefits

Designed for automotive, marine, and industrial fuel systems, this inline gauge helps you diagnose pressure changes, verify line integrity, and fine-tune setups when paired with standard fuel lines. The kit provides a reliable baseline for monitoring during maintenance or testing.

• Automotive diagnostics: monitor fuel pressure in engines and fuel rails for diagnoses and adjustments.
• Marine applications: observe pressure during engine operation to prevent lean conditions and lean outs.
• Industrial systems: integrate into test benches or service bays to verify consistent delivery.

Note: While the gauge helps you observe pressure trends, results depend on your specific system and conditions. Use it as a guide alongside other diagnostics for informed decisions.

Installation is straightforward on compatible lines, and the kit includes essential hardware for a clean fit. The stainless steel body ensures longevity in harsh environments, while glycerin-filled internals reduce needle flutter, preserving readability during vibration.

Choosing Boltigen means reliable readings and a clear view of your fuel pressure landscape, whether you are diagnosing a vehicle, a boat, or a workshop rig.
