I have a new Fimco 60 gal. pto sprayer that works great until I run it dry. I then have to remove the discharge hose to get the 6500C pump to reprime. The valve to the boom is open, outflow part of pump is up, tank full. No obvious constriction in any line (unit is only 1 month old.) Is there some secret to getting the roller pump to self prime?
Many thanks.
