All fuel lines forward of firewall are Aeoquip "hose barbs". Considering inside area of 3/8" hose (0.11 sq in) and 80 psi (more than twice my normal operating pressure) and how hard it is to press on the hose onto the fittings, a 9 pound pressure trying to press off the hose seems minor. I'm more concerned with the quality of the filter (can) itself. With all the high pressure car EFIs out there it should be possible to find a filter with hose barbs -- but maybe not the quality of the Aeroquip ones.
