The
Perkins prima m50 on the amel santorin has the same intake silencer attached to a 50 cm corrugated tube. There is also a tube connecting with the
oil filler stack, which delivers a small amount of
oil to coat the corrugated tube. This in effect creates an oil bath filter catching most, if not all airborne particles. The system has worked fine for 21 years, the Lump has about 6000 hours up on the clock and going well. Regards Joe
