Chasing 0455 Code 2007 Chevy Burban
Hello, I am hoping someone can help. I have had 0455 fuel leak code for months. System has been smoked. Purge valve was replaced. Vent valve has been replaced twice. New gas cap. Tank was even dropped the last time. When I get out of the truck I can small gas and usually a week or less after leaving the shop the light is back on. The gas smells funny, so they thought maybe it was the Sams Club fuel I was using. I run 87 octane with 10% Ethanol. After last repair I have only been using top tier fuels. Anyone have any ideas? Truck is an 07 Suburban with 5.3 Flex motor.
