Fuel Gauge Voltage Stabiliser for VW Beetle 1967 on VW T2 Bay 1973–1979

Can't trust the fuel gauge on your VW T2 Bay or Beetle? It may be a faulty voltage stabiliser. A vehicle's supply voltage varies considerably depending on the state of charge of the battery, the engine speed and the demands made by other accessories. The fuel gauge measures the voltage put out by a sender that responds to fuel level – any variation in the supply voltage causes these readings to change. Stabilise the voltage and you get a more accurate reading.
