Original Vespa fuel taps can be problematic. The rate of fuel flow becomes an issue whenever one modifies or tunes their engine. The golden rule for for uprated engines has been 400ml/min in order to sufficiently supply the engine with enough gas/oil mixture.
BGM faster flow fuel taps flow at an incredible rate of 900ml/min!!!
The new BGM faster flow fuel tap more than doubles the fuel flow from other fast flow taps and triples the amount compared to the original. This makes it an ideal addition to all the powerful setups and provides a secure base to supply gasoline to prevent problems.
