drkrider Posted October 12, 2010 Report Share Posted October 12, 2010 All the operators I've talked to are having the same problem with the Aux fuel pumps failing every few hundred hours. I've talked with the manufacturer and they tell me the problem is their pumps are a vane type pump with a 2/10th of a thousandth of an inch clearance between the case and the vanes and the factory gascolator on the Raven II's isn't fine enough to stop bits sand etc. from getting in and jamming between the case an the vanes loading up the motor and burning it out. Does any one know of an STC'd inline filter that could be installed? Thanks Sean Quote Link to comment Share on other sites More sharing options...
