You are big and strong -- *much* stronger than an eentsy little hose clamp. I don't have a torque figure, and I don't know how to describe a sense of how much force is appropriate for small parts. Working on a bicycle would be good training. I'm tempted to say that this is one of those questions where if you have to ask it the answer is "no." But for a clean new clamp of the proper size, I would say that if you're averagely strong you should be able to tighten it sufficiently using thumb and two fingers on a screwdriver with a one-inch diameter handle. If the clamp bends or strips out the screw, that's a good deal too tight. Sorry not to be more help.

Absolutely. Several times is maybe excessive. Maybe once when firing up, once after first ride? Maybe a month later for any signs of chafe? If there was a problem with the pressure end of it I'd expect it to show up rather promptly, and the fuel pressure is steady regardless of what the engine is doing. d David Beierl - dbeierl@ibm.net |
