Fuel vent

Post by Andy Garrett » Mon Mar 31, 2014 8:33 pm

So this is my fuel vent. It has two holes, and both exist on the same half of the cylinder. Should these holes face forward, aft or to the side for best function? The vent is on the forward deck and the Zip is powered by a 50HP outboard.

If you have it on the deck I would face it aft and perhaps put a cover over it so rain wont get in. It really would be better with the holes facing down

Not sure on top of the deck was a good place to put the vent. Did you put a loop in the hose to keep water out.
I put mine in the side and down some so I could put a loop in the host and attach it to the deck so water would run back out the vent in case any got in. Faced it towards the back of the boat.
Is it on the front deck.

one with the splash guard is good for a deck mount and less harsh on body parts tripping over it

I used that same vent you show Andy but I put it on the side of the boat just under the sheer with the holes facing down and aft and the hose running uphill under the deck before going into the fuel tank so any water that might splash in the screens just gravity flows back out.

Hmmm..., great responses.

Need to re-think... :?

I don't fancy the idea of moving the vent to the side of the boat for a variety of reasons. I do like the vent with the splash shield and may get one of those assuming it'll fit the same hole.

I may choose to cover the vent with a clamshell as well.

The hose will have a loop and I might splice it with a drain plug at the bottom of the loop. That might be the best solution of all.

I was about to order the Perko 0506 vent that Billy pictured above when I stumbled onto the Perko 0570 shown here:

This one has 360* coverage from splashing and intuition told me that it was a better choice for a deck mounted vent. However..., it's ugly. So, I called Perko and talked to a tech about my instalation intentions. They indicated that either would be fine and splash resistance would be equal for deck mounting. I'm not certain I agree, but I will yield to their expertise and buy the prettier one (0506) with chrome and cool angles.

I will still loop the hose and if I ever find water in it, I may switch vents to the 0570.

Hi
I wondering why you need a fuel vent with an outboard? Are you talking about installed fuel tanks or the portable tanks that come with the motors? Or is it necessary when the motor well area is completely enclosed?

Most of us in the Zip/Malahini size outboard boats are running non-portable tanks and thus need a fuel vent line overboard. The tanks are usually located in mostly enclosed spaces somewhat close to electrical components.

All gas tanks have some sort of a vent. It could be external connected by a hose or built into the cap. It is needed so that the fuel pump can pull fuel from the tank. And not pull a vacuum

Flash, My 13gal tank is mounted under the foredeck. It is not the portable type.

I got the vent and could not be more disappointed. It's worse than the open Moeller vent that is pictured first. The black plastic 'splash sheild' will actually work like a bowl to catch water. The vent screen is flush with the bottom of that bowl. Worst possible vent for a deck mount--period.

What disappoints me most is the 'expert technical advise' Perko gave me. "Oh yea, that's perfect for what you want to do."

I can't really think of a 'good' application for this vent--even on the side.

I should have bought the round black one. At this point, I will fabricate a solution or modify the Moeller to work for me.
