I just received a pair of Frontrunner 10.5 gallon upright watertanks which will be bolted to the inside walls of our trailer.. I also received the hose kits complete with the Raco quick connect couplers.... I talked to Brian at Frontrunner USA, about those Raco connectors and was informed that most any garden store or big box retailer has nozzles for the Raco,, I've searched everywhere for Raco accessories to no avail.. I found this part on Raco's website but cannot find it for sale anywhere " original mini nozzle # 55378. Does anyone know where I can purchase 2 or 3 of these nozzles??? Thanks
