Dellorto Petrol Pulse Pump

Fuel pump to fit the Sherco trials bikes from 2010 on.

This impulse pump works on pressure pulses from the engine inlet, these pulses move a diaphragm inside the pump which pushes and pulls petrol through two one way valves providing a steady flow of fuel, It also includes a pressure relief valve to prevent over fuelling.
