Hi, I bought the IAP hose kits for the short 2" rail hoses. I can see a single bolt that holds the rail in place on the block. If I remove this and pull the fat black intake hose, will this be enough to let me replace the hoses? Also, will the hoses just slide off? I will cut to length the 7.5mm hose and place the ends on the "outlets" and then slide the hose sections into them. Do I also need hose clamps? I dont have any kind of crimping tool for the bosch hose ends from the kit. Any help would be appreciated.
