Read my 300 series head question and response down on the page farther. If you don't find it respond again and I'll tell you the cheapest quickest way to get the problem solved. I won't take the credit for the idea though, but I'll give the advice you need. I have bought a twenty foot section of pvc or something similar at the hardware store for around $4.00 or you could use suction hose like it the tip section, under upgrades to header. Curt
