Small block chevy - Mechanical fuel pump.
Had some flooding issues last week. 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.

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

Might also check your fuel line routing, if it's too close to the engine it could be boiling the gas. 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.
