The reason you need this is on the 3400 engine, the low side port is in a really hard to get to place, so you do need a holse this long. I like having the gauge. This product was easy to use (although I had lost of experiece with the old R-12 cans as well). It appears to be good quality, although someonce on Autozon'e website said that the piercing the can par broke after three uses (that's why you save the reciept).
