Manchester Tank Co Gauges & Sending Units: Precision LP Gas Monitoring

When you need to know exactly how much propane is left in a tank, the quality of the gauge and sending unit matters just as much as the tank itself. Manchester Tank & Equipment Co. — a name synonymous with pressure vessel engineering since 1946 — brings that same deep expertise to the Gauges & Sending Units category, offering components purpose-built for their own LP gas cylinders and compatible tank systems.

Manchester Tank's sending units are engineered for LP gas applications, including the popular RV and motorhome propane systems where reliable fuel-level readings directly affect safety and trip planning. Their lineup includes screw-in and snap-on style fuel level gauge sender units — such as part numbers like G12845 and G12846 — which use magnetic activation to communicate propane levels to a dash or panel-mounted dial gauge. The G12846, for example, is a 90-degree remote sender unit designed for tanks equipped with a snap-in sight gauge, making it well suited for tight-clearance installations common in RVs and on-road propane systems.

What sets Manchester Tank's gauge and sending unit hardware apart is the engineering pedigree behind it. As a manufacturer of DOT-approved cylinders and ASME pressure vessels, Manchester Tank designs accessories and components to work in concert with their tank systems — not as afterthoughts. Their sending units are rated at 90 Ohms, a standard resistance range that ensures compatibility with a wide variety of panel-mounted LP gas gauges already in the field.

Manchester Tank's commitment to measurement accuracy extends to their broader gauge strategy as well. The company has moved toward Rotarex electronic capacitance gauges as standard equipment on larger tanks — technology that delivers continuous, accurate propane readings with no moving parts and eliminates the stuck-gauge failures that have long plagued analog dial designs. This forward-looking approach to precision monitoring reflects the same standards customers can expect from their sending unit components.

• Magnetic activation — no direct fuel contact, improving longevity and safety
• 90 Ohm resistance standard — broad compatibility with LP gas panel gauges
• Multiple fitment styles — screw-in and snap-on configurations for various tank designs
• Made in the USA — manufactured to DOT and ASME quality benchmarks
• Direct OEM fit — designed to work seamlessly with Manchester Tank cylinders

Whether you are restoring an aging RV propane system, replacing a faulty sender on a motorhome, or maintaining a fleet of on-road LP gas vehicles, Manchester Tank's sending units deliver the reliability and fit you expect from a manufacturer with over 75 years of pressure vessel experience.
