[Oil pumps] - How do you convert a BFP11 pump from 1 to 2 pipe operation?
- Remove the four hexagonal 4mm screws from the face of the oil pump.
- Then remove the 2.5mm hexagonal screw located at six a clock on the bottom face of the pump.
- Underneath that screw is a copper horseshoe washer, if you require 2 pipe operation you must remove this washer.
- Then replace the screw and reassemble the pump being careful not to trap the pump face gasket.
