In a message dated 98-02-24 18:55:02 EST, you write: << The Racor engineer told me that the 500FG is way too large for the 135hp Lehman. The fuel flow is so slow that the water separator will not work. >> This information is of great concern to me. I checked the fuel filters I have and they would all have the same problem the Racor engineer mentions!! As these fuel filters were installed with the engines it would seem no one is or was aware of this issue. These are the configurations I have: Ford Lehman 225HP with a Racor 900 estimated consumption 5.5-6.5 GPH Isuzu for Hydraulics:Racor 500; est. consumption 2 Gph Onan generator; Racor 500 est. consumption 1GPH Does any one have confirmation of this data? Frank (&Maude) soon on board "Horizons"
