anyone know if the small 90 degree piece of hose included with the pump kit is submersible 30r10 hose ? the curly and straight piece included definitively are not. but the 90drgee piece says 30Rsomething and can make out the rest because its cut could be 30r10 or possibly 30r9 , currently installed the pump with it but if its wrong i need to know asap so i can get a proper one installed .
