Product Overview
A missing cap, cracked seal, or cap that no longer clicks can trigger a loose-cap message or small EVAP-leak code even when the rest of the vehicle runs normally. This replacement seals the filler neck on the applications that use the same thread and pressure-vacuum design.
A gas cap is not the only cause of an EVAP code. Inspect the filler neck and seal and allow the vehicle several drive cycles after repair; leaks elsewhere in the system need separate smoke testing.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown. Model names alone may not guarantee fitment. Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.
Frequently Asked Questions
Q: Can this turn off a check-engine light? A: It can when a leaking cap is the cause, but other EVAP leaks will remain.
Q: Does it fit diesel Ram trucks? A: The researched listing specifically excludes diesel Ram applications in the broad fitment range.
Q: Why is the model list broad? A: 52030377AB is used across many Chrysler-family vehicles; the original cap number and filler neck are the final checks.
