The Dehne fuel gauge is already available since the fifties as an accessory for Type 1. Due to the fact that most of the VW Beetles arent originally equipped with a clear fuel indicator, this fuel gauge is quite popular. Nowadays its better not to be confronted with an empty fuel tank and thats why many people are looking for a suitable solution to install a fuel gauge in our classical cars. Vintage Speed has now an adequate solution with retro look and reliable functionality. 1. Beetle from 1950~1960 use an 11" long Electric VDO sending unit BBT # 0493-5002.
