I need a little sanity check here....
I spent most of Sunday AM doing the pre-winter maintenance on my B2710 (oil change, coolant drain/flush/fill, air filter, etc.) This year I also decided to replace the fuel filter since I'd never done it before...
No problems until I got to the fuel filter - seemed easy enough, just flip the shut-off valve, remove the bowl, replace the filter and re-install the bowl. I even got smart and removed the bowl while holding a can under/around it to catch any drips...yeah, drips. /forums/images/graemlins/frown.gif
Once I got the retaining ring for the bowl loose, the diesel started flowing and I couldn't figure out where or why... I had the new filter right next to me, ready to go, so rather than take any time to analyze the situation, I just put everything back together as fast as I could. As I was putting it back together I noticed the stream of diesel flowing from what appeared to be a third hose into the filter assembly.
After cleaning up the mess I took a look and there appears to be a small vertical hose that comes down from the fuel tank as well as the 2 main hoses (one from the tank and the other to the engine). After reading all of the back posts I could find on the subject (hindsite is a wonderfull thing /forums/images/graemlins/smirk.gif) I found a post from Sept 2, 2001 that discussed a similar experience.
The general consensus at the time was that this third tube was a vent tube for the tank, but no one could explain why it would have been leaking fuel... If this tube is indeed a vent tube I may have an explaination for this phenomenon. My fuel tank was full right to the top when I attempted this feat. The level of the fuel would have been at or over the level of any vent tube and I'm guessing that with less fuel in the tank I would not have had the problem of fuel coming out of this third tube...
Does anyone have an opinion about this? (I know...rather a silly question to ask on this board /forums/images/graemlins/grin.gif) I'm looking for some confirmation that I've got this figured out...
Thanks...
