Polaris 380 Feed Pipe Assembly. This is Polaris OEM Part Number 9-100-7003. This feed pipe is what the hose connects to on top of the cleaner. The ballast float also slips on a stem off the back of this piece. The most common reason to replace this piece is because the ballast stem has broken off, this feed pipe will fix that problem. This feed pipe fits all models of Polaris 380 pool cleaners. This 9-100-7003 feed pipe includes the o-ring that connects into the 380 base. This feed pipe fits the Polaris 380 pool cleaner which has a 3/4" smooth feed hose. Note: If your Polaris has a larger corrugated hose, 1.5" in diameter then you have a Polaris 360 and this feed pipe will not work. The feed hose for the Polaris 360 is a 9-100-1002, check the related products below for a link to it.
