When working on system, I noticed that I have air bubbles showing in glass fuel filter when motor is running, and that filter is only about 2/3 full. Gas tank is under the seat - gravity flow from bottom of tank to pump. All that being said, motor runs strong / no issues. Am I worrying about nothinh here or do I have a fuel pump that is going ? Thanks Guys. | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | normal condition, the filter is never full, bubbles expected .... fuel pumps either work or don't work, be real odd for one to be sucking air without showing up a gas leak when off

It depends on how much Bubbling you have in the filter, if it's a lot like a pot of water boiling on the stove then check your line routing. If it's just a little then it's prob. normal.
