buy all new hoses that go to the carb/heater, i tore a little 'warmup' line from the coolant section, and it leaked it all out, its fun trying to plug a hole, then just take half the intake off of my car for a little thing like that. anyway, all you need is two sockets and an extention(if its a pre 80s) and you need to do is take off #3 & #4 tubes, or #2 & #3, depending on where it is, fairly easy to do, but time consuming,
