300393 Turotest Fuel Gauge | Genuine Used Part

🔧 Product Description

Genuine Turotest Marine Fuel Level Gauge - Part Number: 300393

A genuine used Turotest 52mm marine fuel-level gauge for compatible resistive fuel-tank sender systems.

The gauge is designed to display tank level from empty to full and is associated with the 0-180 ohm sender family commonly used in Turotest and VDO-style marine installations. It should be matched to the resistance direction and range of the existing sender before installation.

⚙️ Key Features

• Genuine Turotest marine fuel gauge
• Correct Turotest part number 300393
• Approximately 52mm instrument size
• Compatible with the 0-180 ohm sender family
• Suitable for 12-volt and compatible 24-volt installations where specified by the instrument

🚤 Compatibility

Commonly used on

• Marine fuel tanks fitted with a compatible resistive sender
• Single-tank and twin-tank installations using one gauge per sender
• Turotest marine dashboard systems
• Boats using 0-180 ohm tubular or swing-arm senders

Typically suits

• Gauge Type: Electrical fuel-level gauge
• Sender Family: Approximately 0-180 ohms
• Instrument Diameter: Approximately 52mm
• Electrical System: 12 volts or compatible 24-volt version
• Engine Compatibility: Not engine-specific

🔌 Function

The gauge measures resistance from the tank sender and converts it into an empty-to-full fuel-level reading.

⚠️ Common Signs of Failure

• Gauge remains on empty or full
• Reading moves in the wrong direction
• Gauge fluctuates while the boat is stationary
• Sender resistance does not match the gauge
• Poor ground or corroded terminals
• Float or sender mechanism is jammed
