bon, je me réponds, trouvé la réponse sur motobrick.
un peu galère néanmoins
1- Remove the gas tank and disconnect both fuel lines from it.
2- Remove the belly pan.
3- Remove the left inner knee panel.
4- Remove the left fairing lower.
5- At the lower front of the fuel rail disconnect the fuel line that runs through the throttle bodies to the fuel pressure regulator.
6- Remove the right inner knee panel.
7- Remove the right fairing lower.
8- Remove the air intake snorkel.
9- Remove the three clips holding the upper and lower halves of the air box together. The right rear one is obvious. The left rear one is somewhat buried and is easiest to access it if you take the top coil cover off and push some wires out of the the way. The front one is "upside-down" and somewhat hidden on the front of the air box.
10- Push the foam heat barrier on top of the air box around to the front to allow a little more upward play in the top half of the air box.
11- Remove the air filter. Note that there is no lip on the left upper edge so the "easiest" way to remove it is to lift the air filter up at the back as much as you can and then pull it straight out to the right side of the bike. (If you're replacing the fuel lines then this is also a good time to consider replacing the air filter - or at least blowing some compressed air through it from the top to clean it out a bit.)
12- Remove the lower half of the air box. Unlike the earlier Ks, the lower air box on a K1100 is not bolted to the engine block so you can pull it right out. It's a bit of a wrestling match though given the tight space. What worked for me was pushing it forward a little, then rotating it counter-clockwise and pulling up and back and out at about a 45 degree angle.
13- Remove the fuel pressure regulator. It's bracket is mounted to the rear of the throttle body assembly at the top via two Phillips head machine screws.
14- Remove the Oetiker clamps securing the two fuel lines to the fuel pressure regulator. (I use a Dremel cutting wheel in the center of the "pinch.")
15- Cut your new fuel line to replace those two hoses. Note that generic fuel line won't have a pre-curved right angle in it on the one to the fuel rail so you'll want to make that one about a half an inch longer than the old one so that it doesn't kink where it connects to the fuel rail.
16- Connect your new lines to the fuel pressure regulator.
17- Reinstall the fuel pressure regulator. Note that the line from the fuel pressure regulator to the tank goes in between the "elephant trunks" for the #3 and #4 throttle bodies.
18- Replace the fuel line between the fuel rail and the gas tank with one of approximately the same length.
19- Put everything back together in the reverse order of how you took it apart.

Cette durit est bien verticale et "disparaît" ensuite derrière la rampe des papillons.
