Thanks guys. I've seen a couple firewall mounts which skirt the hot header pipes. Still not quite sure which way to go with the lines. The full-flow system has me with 3/8 NPT fittings on the block and the remote filter fittings are 1/2"NPT. Wonder if it makes a difference if I go with 3/8" hose or 1/2" hole with reducers at the block or filter mount?
Any suggestions?
