Boltigen Fuel Pressure Gauge

Keep a reliable, vibration-damped readout of your fuel system pressure with this compact Boltigen kit. Designed for center back mount installation, the gauge combines a glycerin-filled movement for steady needle behavior, corrosion-resistant stainless steel and brass fittings, and clamps for a straightforward setup on cars, boats, or industrial machines. It’s built to read low-pressure fuel systems accurately and to withstand everyday engine bay conditions.

How accurate and durable is the Boltigen 0–15 psi gauge?

The gauge uses a glycerin-filled mechanism that reduces needle flutter from vibration, improving reading stability under real-world conditions. Its stainless steel housing and brass fittings resist corrosion, extending service life in mixed environments.

• Range: 0–15 psi for low-pressure fuel systems
• Filling: glycerin to dampen vibration and ensure steady readings
• Materials: stainless steel body, brass barb fittings for corrosion resistance
• Connection: standard 1/8" NPT thread for broad compatibility

What comes in the kit and how does installation work?

The kit includes the gauge, both 3/8" and 5/16" brass barb fittings, and hose clamps so you can adapt to common fuel hose sizes. It’s intended for center back mount placements to keep the dial visible and the plumbing neat.

• Included parts: gauge, 3/8" and 5/16" barbs, clamps for hose securing
• Mounting style: center back mount for accessible dashboard or panel mounting
• Installation: simple inline placement between fuel lines or at a test port using 1/8" NPT
• Compatibility: fits many automotive, marine, and light industrial fuel systems

Which fuel systems and vehicles is this gauge suitable for?

This 0–15 psi gauge is ideal for carbureted engines, mechanical fuel pumps, small marine engines, and any low-pressure fuel delivery system where precise low-end readings matter. It’s a diagnostic and monitoring tool rather than a regulator.

• Automotive: older carbureted cars and mechanical-pump setups
• Marine: outboards and small inboards with low-pressure lines
• Industrial: low-pressure fuel or fluid systems needing real-time pressure checks
• Use case: troubleshooting, tuning, and routine monitoring

How should I maintain the gauge for reliable long-term use?

Periodic checks and basic care keep the gauge accurate: ensure fittings stay tight, hoses remain free of cracks, and the glycerin fill shows no leaks or air bubbles. Replace any damaged hoses or clamps promptly and avoid exposing the gauge to prolonged direct heat without shielding.

• Inspect clamps and barbs for tightness every few months
• Look for fluid seepage or air pockets inside the gauge lens
• Replace brittle or cracked fuel hose segments touching the barb
• Protect from extreme heat sources; mount where airflow reduces temperature spikes

Who is this for: Boltigen’s 0–15 psi glycerin-filled gauge kit is tailored for DIY mechanics, vintage car owners, marine enthusiasts, and technicians who need a compact, stable instrument to monitor low fuel pressures. It’s useful for diagnosing fuel feed issues and for tuning situations where steady, low-end pressure readings matter, and it’s supplied with adaptable fittings to fit a range of common hose sizes.
