Guest ratchethack Posted July 28, 2007 Share Posted July 28, 2007 Correct. It's the ambient air pressure reference for the fuel pressure regulator. Just ignore it. Link to comment Share on other sites More sharing options...
DeBenGuzzi Posted July 28, 2007 Share Posted July 28, 2007 if you start playing with it, you'll be sorrrrrwie. Even if you don't, take it off once in a great moon and clean it or just go and get a couple o-rings cause eventually the thing will leak. It will.

raz Posted July 28, 2007 Share Posted July 28, 2007 Correct. It's the ambient air pressure reference for the fuel pressure regulator. Just ignore it. Wot Ratch said. Though if you really want to do something, you could connect some 5" of hose to it and point it down-back-inwards so it doesn't catch too much moisture and dust. Or at least carefully rotate it so it does not catch every rain drop that falls nearby. Link to comment Share on other sites More sharing options...
pete roper Posted July 28, 2007 Share Posted July 28, 2007 Actually it's the thrunge grommet modulator. The reason it doesn't have a hose on it is because Guzzi couldn't work out whether to use a rubber or plastic hose. Pete Link to comment Share on other sites More sharing options...

Don't worry, Guzzi fired me years ago as a consultant, I could not decide on Tygon or Nitrile, but on my own bike I used vinyl, cause that is what was in my garage. Since they fired me, please note the reliabilty of the Griso, Breva, and Norge Those bikes barely even need a forum!!! BTW, JK except I really did put a vinyl tube on in the way Raz suggested.

When a knowledgable person comes to a point where it is difficult to decide between alternatives, it probably does not matter which one is chosen.

Wise words! I should try to remember that everytime I post about an alternative, and someone shouts, malarky! Link to comment Share on other sites More sharing options...
