Need your opinion. I need to replace the petcocks in the bottom of the Racor fuel filter/water separators. They are seeping slightly. I have new parts. I know I will drain the filter fuel contents as well as fuel from the in and out fuel lines in the process. I carry a gallon of diesel to refill the filters when I change elements. This takes care of most but not all the air I let in. There will still be air in the lines between the tanks and the filters and the filters and the distrubution manifolds (not much volume) when I refill the filters.
Question? Do I have to worry about the air or will it purge itself in the fuel pump and return lines? I know the engines return far more fuel than they burn, so I am guessing I’m OK. What do you think?
