Does anyone know how to clear the fuel vent line on a combination fuel/vent filling neck.

It seems as if the venting takes place through small holes built into the combo unit and that the cap somehow allows for venting when closed.

Trying not to pull the vent from the tank end if I dont have to. Thanks in advanve
 
If you look inside the fuel fill, you can see the vent opening - but it's not easy to blow it out given the location.

But... it's extremely rare for this fitting to get clogged... again, because of it's location.

What's the reasoning for blowing out the line?
 
Faint smell of gas after re-fueling. Primarily in front accces plate area where filler and vent lines are. Boat is 2002. Perhaps new lines are in order as permeation maybe occuring?
 
Tank is probably leaking. Stuff access plate area with paper towels and fill tank. Rock the boat for a while and check the paper towels. Look for leaks around fuel sending unit and hose connections. Alternative is to pull the deck. If the tanks are aluminum at 23 years old it's possible you have a corroded tank.

OK, that helps. I wouldn't worry about clearing the vent line - that's not causing the issue - I was thinking you were having trouble filling up because the line was plugged.

Yes, it's possible that lines can permeate - but the tank leaking and/or the fuel sender plate leaking (as noted above) are more likely.

When you say "front access plate"... are you removing the plate or do you just notice that that general area seems to be where the smell is found?
 
Pull the whole deck hatch. Its just screws and silicone. get a look at the tank and fittings. If you find nothing you will at least be able to clean the tank and know what you have.
You really won't accomplish anything looking thru the pie holes.
