Beetle Fuel Sender + Gauge Stabiliser Bundle Kit - 1968-79 (Also Karmann Ghia - 1974)

This fuel gauge stabilizer unit (also known as a fuel gauge voltage regulator) fits to the rear of the speedometer and ensures a consistent, reliable voltage supply to the fuel gauge on a wide range of classic Volkswagen models. Fitted to all Beetles from 1968–1979, Baywindow Buses from 1973–1979, and suitable for Karmann Ghia, Type 3, and Trekker models of the same era, it prevents erratic gauge behaviour caused by fluctuating vehicle voltage.

On older VW electrical systems, the fuel gauge operates directly from supply voltage, which varies considerably based on alternator output, battery condition, and electrical load. These fluctuations cause the fuel gauge needle to jump, drift, or give inaccurate readings. This voltage stabilizer regulates the current so that the gauge receives a smooth, constant voltage, resulting in a stable, trustworthy fuel level display.

The stabilizer mounts directly onto the back of the fuel gauge within the speedometer housing. Installation is simple and requires just basic hand tools. If you regularly experience fuel level readings that change with engine RPM or electrical load, this stabilizer is likely the solution.

Fitment Notes:

• Installs behind the speedometer on the fuel gauge.

• Replaces original-style voltage regulators on multiple VW models.

• Suitable for both 6v-to-12v converted vehicles and original 12v systems.

Applications:

• VW Beetle: 1968–1979

• VW Baywindow Bus: 1973–1979

• VW Karmann Ghia: 1968–1974

• VW Type 3: 1968–1973

• VW Trekker (Type 181): 1968–1983

This good quality electric fuel sender is designed as a direct replacement for the original unit fitted to standard VW Beetles from 1968 to 1979 (excluding 1302 and 1303 models) and Karmann Ghias from 1974 onwards. The sender provides the correct resistance range for accurate fuel gauge readings—80 Ohms at empty and 10 Ohms at full—ensuring smooth and predictable gauge operation.

Featuring a 5-hole PCD of 54.5mm, this sender matches the factory mounting pattern found on non-Super Beetle fuel tanks. Over time, original senders can corrode, seize or send erratic signals, causing unreliable gauge readings. Replacing the sender restores proper function and eliminates guesswork when checking your fuel level.

Manufactured to a high standard, this sender installs directly into the tank and is supplied with a new seal for a leak-free fit. No modification is required when fitting to the correct models.

Fitment:
• VW Beetle: 1968–1979 (except 1302 & 1303 Super Beetle)
• VW Karmann Ghia: 1974 onwards
• PCD: 5 × 54.5mm
• Resistance: 80Ω empty, 10Ω full
• Supplied with sealing gasket
