I have also had a gassy smell in my 89 4.9L too. I checked the fuel lines and they look good. Any suggestions?

Have the plugs been changed recently? I know you just got the truck, did the dealer mention anything about the plugs??

No im assuming plugs are factory still.

Check your exhaust system for leaks, you can cover the tail pipe with a rag while it's running or pour some tranny fluid down the carb and look for smoke. There is a good possibilty your fuel isn't burning cleanly (spark plugs) and the smell is coming from an exhaust leak.

Ill change plugs this weekend see if it helps.

Check the forum for spark plug removal, I have seen a couple of years with the 5.4 that are a bear to change.

Okay thanks

Bump smell is coming from vents when air is on
