fuel tank?

Recommended Posts

Last year I was using an Attwood plastic fuel tank. I store my boat in the garage and on more than one occasion I came home to a garage and house stinking of gasoline. I'd go out and look at the tank and it was inflated like a balloon.

Is this a cheap tank, or did I get a dud? Is there a fix to this? I'm at a loss, but I know for sure I don't want to have the stink in the house again...

My guess is the cap was on tight (sealed) and the temperature was warmer, that made the gas expand. Make sure the cap is only on 1/2 way (like when it is in the boat), so the pressure can equalize.

Gas vapors expand as they are heated, so you need to provide a means for the tank to expel the expanded gases. Think of it like a jug of water. If you fill it to the top and freeze it, the container will burst as the ice expands. Your gas tank is filled with liquid gas, vapors, and oxygen. As the surrounding temp increases, so does the volume within the tank. Most internal boat gas tanks have pressure release valves. Small portable tanks do not.

I understand how the inflation occurred in the sealed nature of the tank. I was under the assumption that the tank I own had a vented cap of some sort.

As I'm reading around the internet, I'm finding the EPA put a stop on the manufacture of those vented tanks.

Guess I need to remember to unscrew the cap when I get home.

Thanks.

It can be a pain to remember to unscrew the vent when you get to the lake, tighten it when your trailer, and then open it again when you get home. I usually forget the last part

I would see if you could find a tank with a vented cap. That would cure your issues. Maybe one online somewhere even a used one would cure your issues.

    • Heavy rains across northwestern Wisconsin last weekend and early this week have flooded some roads and caused washouts on some highways, roads, state parks, forests and trails. According to the National Weather Service the area has received 7 to 12 inches of rain from Friday through Monday.Several park system property or portions of properties are closed due flooding. Amnicon Falls State Park, closed temporarily but has reopened, though some roads, trails and observation areas remain closed. Pattison State Park is open for camping only; all trails, observation areas, picnic and day-use areas are closed. There are washouts on the dam that forms Interfalls Lake and Highway 35 over the dam is closed. A campground and horse trail are closed at Governor Knowles State Forest and the day use areas along the river at Interstate Park are underwater.Water was roaring over Little Manitou Falls at Pattison State Park.Photo credit: Gervase ThompsonAll rivers in the region are running extremely high. The falls at both Amnicon and Pattison are roaring, but road closures mean observing the falls now is challenging. The Bois Brule and Flambeau rivers are high enough that some canoe launches and campsites are underwater. The water is making its way downstream and the Lower Wisconsin River is running very high with all sandbars submerged and canoeing and kayaking not recommended. The river is expected to crest Muscoda this weekend at 40,000 cubic feet per second. .
    • I'm still going to smoke this fatty while camping this weekend whether Leech likes it or not.....😋       See you fellers on Monday........
    • Rick didn't like all the "My Grills bigger and better then yours" posts!  😅
    • We switched to a new server. Had a glitch in our dB that lost a couple days of posts.
    • I ripped a hole in one of my favorite pairs of fishing shorts just need a decent sized patch to cover her up
    • I am not sure what happened either but we lost all of the posts last couple days not just this thread. And it looks like the same thing happened over on FM site as well. I know the site was down last night while I tried look at it.
    • We had no problems but only brought 10 extra gallons over.  We fished 5 days, pretty much running wherever we wanted and ended with 7 gallons remaining in the boat.  So, we burned 30 gallons of fuel in a 1785 Lund with 90 hp Mercury 4 stroke.   I thought that was pretty good!
    • Seems to me that we are missing an entire page from this thread that was here yesterday.... what gives?
