JonG I cut all that sorry trash out of my manifold,with LPG you dont need it ! Summer or winter! Just this morning went out at 5;20 a.m. fired-up with just a bump,went to coffee shot the breeze about an hour went out fired up with just a bump came home.No vapor-lock,no fuel pump,no gasoline fumes in the cab,never cold natured,no sludge,oil like new,one simple filter !! What's not to like ??
