Seal Your Tank: Vintage Vented, Non-Vented & Locking Gas Caps
Is your garage smelling like gasoline, or does your engine mysteriously die after 20 minutes of driving, only to restart once you open the filler cap? You likely have the wrong gas cap. The fuel cap is a critical component of your fuel system, maintaining the correct tank pressure and preventing dangerous fumes from escaping.
At Old Car Parts NW, we stock authentic NORS (New Old Replacement Stock) gas caps from trusted vintage brands like Stant and Wayne.
Vented vs. Non-Vented: What Do You Need?
Using the wrong cap is a common mistake in restoration.
-
Vented Caps: Essential for most pre-1970 vehicles. If your fuel tank does not have a separate breather tube, the cap must "breathe" to replace consumed fuel with air. If you use a non-vented cap here, the fuel pump will create a vacuum that starves the engine.
-
Non-Vented Caps: Required for vehicles equipped with evaporative emissions systems (typically late 1960s and newer) that use a charcoal canister or separate vent line.
-
Locking Caps: Protect your fuel and prevent vandalism with our vintage chrome locking caps—a must-have accessory for street parking.
Inventory Highlights:
-
Standard Chrome: OEM-style caps for a factory look.
-
Anti-Surge: Designed to prevent fuel sloshing out during cornering.
-
Fitment: Shallow and Deep Cam styles for Ford, Chevy, Mopar, and AMC.
Stop the Leaks: Pre-Bent & Hard Fuel Lines
There is no greater fire hazard in a classic car than a rusty or cracked fuel line. Over decades, moisture in the gasoline eats away at steel lines from the inside out, while rubber hoses turn brittle and crack.
At Old Car Parts NW, we stock NORS (New Old Replacement Stock) and replacement fuel lines to ensure your gasoline stays in the line and off your hot exhaust manifolds.
Pump-to-Carb Hard Lines
The most common failure point is the specialized hard line connecting the fuel pump to the carburetor.
-
Ditch the Rubber: Many owners dangerously replace these with rubber hose, which can melt or burst under pressure.
-
Factory Fit: Our inventory includes correct, pre-bent steel lines with the proper flare nuts for Ford, Chevy, and Mopar engines. They fit around the thermostat housing and alternator exactly as the factory intended.
Inventory Includes:
-
Pump-to-Carb Lines: Pre-formed steel lines for specific V8 and 6-cylinder engines.
-
Flex Hoses: The short, flexible rubber connection between the frame rail and the fuel pump.
-
Bulk Tubing & Fittings: Copper and steel tubing for custom fabrication.
