I am trying to plumb my ugf up to a riser above my tank ( kinda sort of along the lines of a gravity fed " Paul B " design. ) However I am finding a hard time finding 90 degree fittings and couplers to fit my ugf thin wall poly tubing. I was able to find 5ft sections of straight poly tubing at my lfs but no fittings. The hardware stores had plenty of fittings but the diameters did not match up to the thinwall poly tubing ( too loose ) Does anyone know who might happen to sell those fittings or any idea ?
