I have a set (for both motors, 4 pieces) of airseps for 12 cyl man engines brand new in the box never opened,I also have a pair of fuel seps model number wf 9000, these will keep your engine from smoking . the fuelseps are not model specific to an engine . The fuelseps are also brand new in the box never opened. If anyone is interested let me know , thanks
I am interseted in both the fuel seps and air sps. i have 671 detroits. Will these items work and if so, how much are you asking for the various units?
