hello herald. this machine is sending me round the twist. i let the customer use the truck whilst still smoking a fair bit. and it seemed to clear itself after a days work. yesterday morning it wouldn,t start up first thing. went too it and bled fuel systemto get it going. then after 5mins it conked out on me. bled it again. after a bit of deliberation i put a clear pipe from top of tank to lift pump. tried to bleed again and the **** wouldn,t lift fuel. new lift pump and filter head fitted this morning and it,s going like a train ,so here,s hoping it,s cured. regards kevin
