Has anyone had problems or replaced them after so many miles. Do you just clean them :tiphat:
Her they are on Amazon https://www.amazon.com/Airtex-6P1351...Anissan%3A370z

old school just rinse in gas, brake cleaner etc..shake the hell out of it..if u dont hear a ball inside tapping around u may have to replace

Not sure if it still applies but, back in the Good Old Days, we'd just flush them real good with carb cleaner and make sure the check ball was still free (rattled when you shook it). If the ball was stuck, we bought a new one.
