Sea-Dog Stainless Fuel Tank Vent 5/8 In 90 Deg | 352230-1
Sea-Dog Stainless Fuel Tank Vent 5/8 In 90 Deg | 352230-1 — Product description
Every gas tank on a boat needs a vent, and this is the one you want in stainless. Sea-Dog's 90-degree fuel tank vent lets the tank breathe while you fill and while the engine runs, and the downward elbow keeps rain and spray out of the line. Sized for 5/8 inch vent hose.
The Sea-Dog stainless steel fuel tank vent is the fitting that lets your gas tank breathe. Every fuel tank needs one. When you're topping off at the dock, the fuel coming in has to push air and vapor out somewhere, and this is where it goes. When the engine's pulling fuel, air comes back in through the same vent so the tank doesn't draw down into a vacuum and starve the motor.
It's built for 5/8 inch inside diameter vent hose, which is the standard size on most gas tank installations. The body is stainless steel, so it shrugs off salt spray and won't streak rust down your topsides the way a plated fitting eventually will. That matters on a hull side that everyone sees.
The 90-degree elbow is the part that matters more than people think. It points the vent opening down toward the water instead of straight out, so rain, spray, and dock wash don't run right into the line. Water in a fuel vent is how you end up with water in the tank, and water in the tank is a bad day on the water. The downward angle keeps most of it out.
Install is straightforward. It mounts through the hull side, usually near the fill, and connects to the tank's vent barb with 5/8 inch hose and a couple of clamps. The hose and clamps aren't included, so grab those separately if you're running a fresh line. If you're replacing an old corroded vent, match the hose size and you're set.
This is a genuine Sea-Dog fitting. Whether you're rigging a new tank or finally swapping out a vent that's been weeping rust for a few seasons, it's the right part. Not sure it's the size you need? Measure the inside diameter of your existing vent hose and we'll confirm before you order.

Frequently asked questions
What does a fuel tank vent actually do?
It lets the tank breathe. While you fill, it pushes displaced air and fuel vapor out so the tank doesn't pressurize. While the engine runs, it lets air back in so the tank doesn't pull a vacuum and starve the motor. Every gas tank needs one.
What hose size does this fit?
It's built for 5/8 inch inside diameter vent hose, which is the standard size on most boat gas tank installs. Measure the ID of your existing vent hose to confirm before ordering.
Why is the vent angled 90 degrees?
The elbow points the opening down toward the water instead of straight out. That keeps rain, spray, and dock wash from running right into the vent line, which is how water ends up in your fuel.
Is it really stainless steel?
Yes. The body is stainless, so it holds up to salt spray and won't leave rust streaks down your topsides the way a plated or chromed fitting eventually will.
Does it come with the hose and clamps?
No, this is the vent fitting only. You'll need 5/8 inch vent hose and a couple of clamps to complete the run. Grab those separately if you're rigging a fresh line.
Will it work on a gasoline tank?
Yes, it's a fuel tank vent sized for the standard 5/8 inch vent hose used on gas tanks. If you're unsure about your setup, send us the details and we'll help you match it.
