Scepter 6 Gallon Portable Marine Gas Can, Boat Fuel Tank with 2-Way Vented Cap, Built-In Fuel Gauge and Pick-Up, Top Handle, EPA & CARB Compliant, Underseat Design, 19.3"L x 12.2"W x 10.2"H (10511)

Dimensions were exactly as stated on the listing. The non-vented cap doesn't bother me like it seems to bother others making reviews. That's the EPA regulations they are trying to meet. There is no gas fitting on this tank and if you want to install a gas fitting that is right angled instead of straight, you have to loosen all of the bolts that hold the fuel gauge section on the tank so you can twist your fitting on. I'll be buying a second one since I want 12 gallons on the boat, but will simply swap tanks when one runs out. The 6 gallon is much easier to lift in and out of the boat for refill.

Fits perfect on a 2023 mako proskiff 17

Works Fine

I got this 9 gallon tank to replace the 5 gallon tank in my boat.I wish it was about 1 inch longer and 1 inch wider. Really needs to be about 1-2 inches shorter in height for my boat.Built in fuel gauge on top of the tank. Has not leaked that I know of. You'll have to put a fuel line fitting on it. It doesn't come with one.I doesn't come with straps to keep it from sliding around. Buy them separately.Nice fuel tank. Be sure and read the dimensions in the description and measure the area in your boat where you want to put this. I'll have to make a few modifications to make it work, but I'll appreciate the extra 4 gallons of gas while on the water.This tank does swell and pressurize with gas in it. It is plastic.

Very cool tank , excellent quality, love the fuel gauge well worth the money. Takes a 1/4” NPT fitting.

Bought this before Xmas last year and wasn't planning to use it til boating season so now that it's here I have 2 serious issues and it's out of any return window!!! 1st major issue was after it was filled up and tilted towards the gage it pissed out gas around the whole unit. Took it apart only to find a flimsy rubber gasket so I put permatex 2 on top and bottom of gasket and no more leak so on to the breather valve issue....thier system doesn't work so I clipped the tip off the little rubber piece on the inside part of the cap, after doing that I shook it up real good and left it in the sun and cracking the vent I could actually hear it relieving the pressure. Horrible unit so do not buy!!!!!!

Tank looks to be well made just installed. Leaked through the plug hole but cured the problem after installed the twist lock connector that has a check valve. With expansion of fuel it will come out with no restriction because this is the fuel pick up. This is the reason for videos of leaking tanks and should be explained in instructions.

I've got two of these on my Whaler Montauk. Snug fit under the seat. But these tanks keep me on the water all day.
