Komatsu PC300lc7-L air in fuel

vendredi 1 août 2014

Ok I bleed out all o the air from the fuel system. Runs great, but as soon as you shut it off it sucks air again and you have to bleed it to get it to start. Replaced all crush washers at banjo fittings and a new lift pump. cannot find any obvious leaks. I am about stumped. The new crush washers are from Komatsu and are metal with rubber o-rings inside. I question the new ones and am thinking about replacing them all with copper washers. Any Ideas??????
