I have a 450 ,07 Rihno and it runs great and pulls rocky terrian very good.   
When going down a Steep Rockey incline sometime the enging Quits.
When I went to see if I had ran out of fuel their was a VACCUME in the tank and I thought it would suck my hand into the tank.
Has anyone had this problem with their Fuel Tank getting a vaccume in it.
Does anyone know if their has been a recall on bad fuel cops for ,07 models :?:
