    Stbd fuel tank vent

    I believe I have a clogged fuel tank vent on the stbd on my 2001 380. Went to fill up today and put 15 gallons in and got a gush of air and gas out of the fuel fill. Luckily I always have a rag in my hand, just in case so I was able to catch the fuel before it went anywhere. How difficult is it to change the through hull fitting? Does it unscrew, twist off, etc? My guess is that the screen is oxidized and blocked. Also, is the best way to the tank top connection through the gunnel access panel in the aft salon?

    Can't help you with access on your boat, but...

    Visually check the screen before you go and buy a new one. It could be plugged with old wax or spider webs.

    Another thing that you should verify is the pathway of the vent line from the tank to the fitting. Be sure it continually goes uphill and does not have any dips in it

    I am having the same issue and am sure it's wax build up. How do you clean the vent screen? Does it come out?

    Not sure about the 380, but, on the 410, in the aft cabin starboard cabinet, there is an access panel with 4 screws in it that lets you get to the vent hose.

    You may want to look to see if yours is similar.

    both boats i have owned do this as well...i just thought it was 'normal'.....i try to 'listen' to the escaping air from the vent tube as i fill the tank....i can usually tell when the tank is almost full by the change in sound from the vent tube....then i slow the filler hose down the last little bit to avoid a splash out of fuel....but sometimes i still get the 'splash' of gas out of the filler neck....

    is this normal or do i have a problem that needs to be fixed?....

    Re: Stbd fuel tank vent

    Mine did this at the last fill up. It did it at the start of the fill up... burped... then was fine. First time it has done this with fuel. Almost always does this when filling water tank. but only at the start.

    Funny mine did the same thing yesterday on both sides. I have filled up twice already and this was a first. Interesting, I will check my screens.

    Re: Stbd fuel tank vent

    I did indeed have a blocked vent. Spiders and wax were the culprit. I accessed the vent line at the top of the tank and blew it out. Admiral was mortified at the amount of junk we got out. Filled the tank with no issues and seems to be fine. I blew out both sides just in case but I am thinking that the angle of the fill into the starboard tank makes it more susceptible to burping than does the port. I will, at some point this season need to replace the screens. My guess would be that the easiest, if there is such a thing, would be to replace the entire through hull. Any other suggestions are graciously welcomed!

    Thanks for the responses and suggestions!!

    Get a spray can of carb / choke cleaner with the red straw and spray the screen it will dissolve the wax
