Internal tank (88 Bayliner Capri w/85 HP Force)

[givener]

Pardon me for what may be a dumb question, but my new boat is the first I've owned with an internal fuel tank. I am all too familiar with the embarassment of stalling after forgetting to unscrew the vent cap on a portable tank, but what is the procedure on an internal tank? I was recently having problems possibly tied to fuel starvation and unscrewed the gas cap for lack of a better idea. How is an internal tank ventillated to prevent vacuum buildup? How would I go about checking for obstructions in the vent line, etc. Thanks.

There is an "always open" vent, which is usually plumbed out the stern of the boat.
Has a slotted cap over it to discourage water from going in, and to prevent insects from making a home inside.

You can push a wire inside, or blow air through it, but that will likely push any obstruction in the hose, into the fuel tank.

If obstructed, you can remove the hose, clean it, and re-install.
