hi I have a 2002 elnagh marlin motorhome on a 2.8 diesel fiat ducato chassie. during a recent trip I started up my van after being parked up overnight travelled 500 yards and found fuel pouring out from the bottom of the fuel filtre it didnt last long and i lost about half ltr I cleaned up the area and found the fuel had been coming out a plastic tube next to the electric plug at the bottom of the fuel filtre. ( is this somekind of overflow ? ) have not had any repeat of this problem even after travelling over 300 miles .....was this some kind of blockage that purged its self ? ...any ideas anyone
