Morgo Triumph Plunger Oil Pump

The plunger pump is a copy of the factory-fitted item, as found on Triumph twins. However, Morgo units offer more efficient operation & a lower sump oil level during running due to a higher scavenge flow rate. The plunger pump has a brass body with hardened steel plungers & sliding drive block.
