Gas Tank Vent Hose; 78-8 6 Jeep CJ Models - Rubbe

The Gas Tank Vent Hose for 1978–86 Jeep CJ Models is an OEM-equivalent replacement component that restores proper fuel system ventilation in classic and restored CJ platforms. As a mechanic who has rebuilt countless vintage Jeeps, I can confirm that fuel tank vent integrity is often overlooked—yet it's critical to preventing fuel starvation, pressure buildup, and carburetor flooding during operation. This OMIX-ADA vent hose is engineered to match original specifications, ensuring your CJ's fuel system breathes correctly during acceleration, deceleration, and varied terrain.

Constructed from durable natural rubber, this vent hose is designed to withstand the thermal cycling and fuel vapor exposure inherent to vintage fuel systems. The hose routing and diameter are calibrated to allow air to enter the tank as fuel is consumed, preventing vacuum lock that can starve the engine or cause erratic idle and stalling. At 15.7 inches in length with a compact packaged size, this hose integrates seamlessly into the OEM charcoal canister or vent line path used on 1978–1986 CJ models, maintaining the original emissions and safety architecture without modification.

Restorers, off-road enthusiasts, and daily-driver CJ owners benefit most from this replacement when addressing fuel delivery issues or performing routine fuel system maintenance. If your CJ exhibits sluggish acceleration, vapor lock, or difficulty starting after sitting, the vent hose is often the culprit—especially on vehicles with original rubber now brittle or cracked. Installation is straightforward: disconnect the old hose from the tank and charcoal canister, then route the new OMIX-ADA hose following the factory path. This single component can transform your CJ's reliability and driveability on pavement and trail alike.
