Thank for the info. I just happen to have purchased DP from Phil last week o I believe I will give it a shot. Along this line and not to hi jack this thread. I believe that some air is being pulled into my fuel system ( hoses soon to be replaced). With the engine at idle ( smoother now that I adjusted the rack dampener bolt) I see constant small air bubbles coming into the small clear prefilter. It might just be the clamp. However thought I would ask should I see any ? It has a little white smoke at start up and slightly rough then clears up quickly.
Thanks
Alan
