Product description
Built To Order
13mm pumps are competition pumps and are prone to stalling, over fueling and must be fed by a large lift pump like Fass or Airdog 200GPH. 13mm pumps are very sensitive to fuel supply and delivery. The plunger/barrel assembly is lubricated by the fuel. Lack of fuel supply to the pump can seize the plunger. Often builders will lap the internals a lot and it will create a hard start 13mm. Our builder does a mild lap to avoid the hard starting. If you want a more aggressive lap to allow for greater clearance and use comp cut, 1/2 cut or full cut delivery valves please note and we will build the pump that way.
