Check any of the rubber fuel lines going to the filter head to the ficm or check the valley for wet spots, could be some of the rubber return lines. Could be dry rotted. :thumb:

Yes. The lift pump is only a band aid for this problem. It's still getting air and will probably slowly get worse.
X2 if the lift pump failed for whatever reason... it might live you stranded on the side of the road... fix the air leak...weather it be the fuel filter housing... bad filter or rings...
May want to spend the 20 or 30 bucks and rebuild the fuel filter head. Mine was doing the same exact thing, but it was the WIF sensor petcock leaking. I just put a billet plug and solved the problem
x2 on the head rebuild. or get a airdog and eliminate the factory filter head all together if in fact thats where your air is coming from..
X3 on rebuilding the filter head. I rebuilt mine with orings from the store and have no problems with it.
its not leaking fuel anywhere, i know that, its the first thing i checked. just thinking bout getting an airdog twin lift pump.
Also keep in mind tht if you have a leak that is letting air in, when you pressurize the system with a lift pump that same leak will now let fuel out. Check your fuel lines up at the engine, and also rebuild your filter head like stated above.
Most of the fuel system is under a vacuum because the pump is on the motor so you will not see any fuel.
Find the leak!
Did this start just after you changed the fuel filter???
