Overview

Meet the Marshall MNB00100 Fuel Pressure Gauge, a compact yet rugged instrument designed to deliver steady readings in demanding conditions. Its liquid filled chamber dampens vibrations, helping the dial settle even when equipment runs rough. The gauge reads from 0 to 100 PSI and uses a 1/8 inch NPT center back connection for straightforward installation in a variety of systems.

Why it stands out

With a black dial and a vivid red pointer, visibility is excellent at a glance, even in low light. The liquid filled design reduces needle jitter, which can make readings feel more reliable during pulsating operation. The black case and bezel add to its durable, professional look.

Applications you may consider

The MNB00100 is suitable for air, oil, and fuel, as long as the medium is not corrosive to copper alloy internals. This makes it a versatile choice for automotive diagnostics, small engines, generators, marine gear, and other equipment where pressure checks matter.

  • 1.5 gauge face, 0-100 PSI range, 1/8 NPT center back connection for common retrofit scenarios
  • Black dial with a red pointer and a liquid filled housing for improved readability
  • 12 month satisfaction guarantee with replacement or refund if needed

Installation and maintenance tips

  • Use a HEX wrench to tighten or loosen the connection on the stem; avoid turning the gauge case
  • Apply thread sealant and test the connection for leaks before pressurizing
  • Do not operate if a leak is detected or if conditions exceed the top scale, or involve excessive vibration, pulsation, high temperature, or corrosive media

What you gain

Expect clear readings, durable construction, and flexible mounting in a compact package. While results can vary by setup, this gauge is designed to support quick, informed checks as part of routine maintenance or diagnostic workflows.

FAQ

Q: What media can the Marshall MNB00100 gauge monitor?

A: Suitable for air, oil, and fuel, as long as the medium is non-corrosive to copper internals.

Q: How should I install and maintain the gauge?

A: Tighten with a HEX wrench on the stem, apply thread sealant, and test for leaks; avoid exceeding the top scale.
