Whitecap Gas Deck Fill No Vent Straight #S-4423NV
$169.73
$215.57
Whitecap S-4423NV Deck Fills
The Whitecap S-4423NV is a straight, 0-degree gas deck fill built from 316 stainless steel and designed to handle the demands of a marine environment without complaint. The sculpted flip-top cap gives it a clean, low-profile look on deck while keeping a positive seal when closed. No vent means this is a pressurized fill, so it pairs with fuel systems that manage venting separately.
316 stainless steel is the right call for anything living on a boat deck. It holds up to salt spray, UV exposure, and the general abuse that comes with life on the water far better than chrome-plated zinc or lower-grade stainless. The straight (0-degree) neck makes installation straightforward in applications where the deck surface is flat and the fuel tank fill neck runs directly below.
The flip-top cap design is a practical detail. It opens with one hand, stays out of the way while fueling, and snaps back down securely when you're done. No loose caps to lose overboard, no fumbling with a key or coin slot at the fuel dock.

Whitecap Gas Deck Fill No Vent 30-Degree #S-4423A30NV
$171.46
$217.76
Whitecap S-4423A30NV Deck Fills
The Whitecap S-4423A30NV is a 30-degree angled gas deck fill made from 316 stainless steel, built for marine fuel systems where a straight neck just won't work. The 30-degree offset is the key difference here -- it gives you the clearance needed when your deck angle, tank position, or hull geometry makes a straight 0-degree fill awkward or impossible to install cleanly.
Like the rest of the S-4423 family, this fill features a sculpted flip-top cap that opens with one hand and locks back down with a solid snap. No vent means it is designed for pressurized fuel systems that handle venting through a separate dedicated vent fitting. The 316 stainless steel construction resists corrosion from salt spray, fuel exposure, and UV without needing much attention beyond a rinse.
The angled neck makes routing the fill hose to the tank more manageable in tight engine compartments or where the tank sits off-center from the deck fill location. If you have been fighting a kinked hose or a fill neck that fights back during installation, the 30-degree version is worth the look.

Whitecap Gas Deck Fill with Vent 30-Degree #S-4423A30
$201.25
$255.61
Whitecap S-4423A30 Deck Fills
The Whitecap S-4423A30 is a 30-degree angled gas deck fill with a built-in vent, constructed from 316 stainless steel. It is the vented counterpart to the S-4423A30NV, and the distinction matters. If your fuel system does not have a separate dedicated vent fitting, this is the version you want. The integrated vent allows fuel vapors to escape during filling, which keeps pressure from building up in the tank and makes the fueling process smoother and safer.
The 30-degree neck angle gives you flexibility during installation. When the deck is not flat above the tank, or when the fill hose needs to make a turn right out of the gate, the angled neck reduces stress on the hose and makes routing cleaner. Pair that with 316 stainless steel construction and a sculpted flip-top cap, and you have a deck fill that handles the job without adding maintenance to your list.
The flip-top cap opens with one hand and snaps back down securely when closed. No loose cap to chase across the deck at the fuel dock. The polished stainless finish holds up to salt, fuel spills, and sun exposure without pitting or staining under normal use.

Whitecap Gas Deck Fill with Vent Straight #S-4423
$199.51
$253.40
Whitecap S-4423 Deck Fills
The Whitecap S-4423 is the straight, vented version of Whitecap's 316 stainless steel flip-top gas deck fill. The 0-degree neck runs straight down, making it the right fit when your deck is flat and the tank fill neck sits directly below without any offset. The integrated vent is built into the fill body, so fuel vapors have a path out during fueling without needing a separate vent fitting elsewhere in the system.
That built-in vent is worth paying attention to when spec'ing your fuel system. On boats without a dedicated tank vent, this fill handles both jobs cleanly. On systems that already have a vent, the no-vent version (S-4423NV) is the better call to avoid over-venting. If you are not sure which your boat uses, check the fuel tank before ordering.
Construction is 316 stainless steel throughout, which holds up to salt air, fuel exposure, and deck traffic without corroding or pitting. The sculpted flip-top cap opens with one hand and snaps shut firmly. It stays put underway and does not rattle loose over time the way threaded caps sometimes do.

Whitecap Gas Deck Fill No Vent Folding #S-1423NV
$82.23
$102.08
Whitecap S-1423NV Deck Fills
The Whitecap S-1423NV is a folding-cap gas deck fill with no vent, built for marine fuel systems that handle venting through a separate dedicated fitting. The folding cap is the defining feature here -- rather than a flip-top that stays attached at one side, the folding design folds flat against the deck when open, keeping it completely out of the way during fueling and reducing the chance of it catching on anything while the nozzle is in.
No vent means this is a pressurized fill. It is designed to work alongside a separate tank vent fitting, not replace one. If your boat does not have a dedicated vent, the vented version is the right call instead. If it does, the S-1423NV keeps things clean and simple.
The S-1423NV sits in the same Whitecap deck fill family as the S-4423 series but uses a different cap mechanism. The folding style tends to sit lower profile when open compared to a flip-top, which some installations prefer depending on the deck layout and how close the fill is to other hardware or the gunwale edge.

$143.12
Whitecap S-1423C Deck Fills
The Whitecap S-1423C is a straight, vented gas deck fill with a folding cap, designed for marine fuel systems that do not have a separate dedicated vent fitting. The integrated vent allows fuel vapors to escape during filling, which prevents pressure buildup in the tank and makes the fueling process go smoothly. If your boat relies on the deck fill to handle venting, this is the version you want over the no-vent S-1423NV.
The straight (0-degree) neck runs directly down from the deck surface, making it the right fit when the tank fill neck sits directly below without any offset or angle. Installation is clean and straightforward in that configuration, with no need to work around a bent neck or angled hose routing.
The folding cap design folds flat against the deck when open, keeping it out of the way during fueling and reducing the profile compared to a raised flip-top. When closed, it seals the fill opening and sits flush with the surrounding deck surface. The cap stays attached to the fill body, so there is nothing to lose overboard at the fuel dock.

$103.99
Whitecap S-1423A30NV Deck Fills
The Whitecap S-1423A30NV is a 30-degree angled gas deck fill with a folding cap and no vent, built for marine fuel systems where the tank vent is handled separately. The 30-degree neck offset is the practical solution when a straight fill neck would create a sharp bend in the fill hose, put stress on the hose connection, or simply does not line up cleanly with the tank below. The angled neck gives the hose a gentler routing path right from the start.
The folding cap folds flat against the deck surface when open, keeping it low and out of the way while fueling. When closed, it seals the fill opening and sits flush with the deck. The cap stays connected to the fill body, so there is nothing to drop overboard at the fuel dock.
No vent means this is a pressurized fill designed to work alongside a dedicated tank vent fitting elsewhere in the fuel system. If your boat does not have a separate vent, the vented version is the correct choice. If it does, the S-1423A30NV keeps the fill side clean and simple.

$114.58
$142.24
Whitecap S-1423A30 Deck Fills
The Whitecap S-1423A30 is a 30-degree angled gas deck fill with an integrated vent and a folding cap, covering the two most common installation needs in one fitting. The 30-degree neck handles situations where a straight fill neck would force a sharp bend in the hose or create a misalignment between the deck fill location and the tank below. The angled neck gives the hose a natural routing path and reduces stress on the connection point.
The integrated vent means this fill handles both fueling and vapor venting in one fitting, making it the right choice for boats that do not have a separate dedicated tank vent. Fuel vapors escape through the vent during filling rather than building pressure in the tank, which keeps the fueling process smooth and safe. If your system already has a dedicated vent, the no-vent S-1423A30NV is the better fit.
The folding cap folds flat against the deck when open, keeping a low profile during fueling and staying completely clear of the fill nozzle. When closed, it seals the opening and sits flush with the deck surface. The cap stays attached to the fill body at all times, so there is nothing to lose overboard.
