Overview
The Jeep 52127601 is a genuine Mopar fuel vapor tube for 4 or 6 cylinder engines with a 15 or 19 gallon fuel tank. It mounts on the engine side.
Vapor line basics
A fuel vapor tube carries fuel vapor between the tank and the rest of the evaporative system, so a restriction or leak can cause odor, rough running or evap-related fault codes. Steel tubes hold their shape and resist heat better than many plastic lines, but the connections at each end are where leaks usually start. Before fitting a new tube, inspect the mating fittings and grommets for cracks.
Engine-side routing sits close to hot components, so keep the tube clear of exhaust parts and moving linkage. When replacing the tube, avoid sharp bends that could restrict flow, and check that the routing matches the old line exactly. Recheck for fuel odor after the first drive, and look for dripping or staining around the fittings.
