Hey how are you,I will try to help you with this issue

if the fuel pump sucking debris from bottom of tank it will cause that

fuel pressure needs checked first ,click on ink to view how to test it and the specs needed

2008 Ford Truck Edge FWD V6-3.5L

Save Article

Item...............................................................Specification Engine running fuel pressure....................................450 kPa (65 psi)

there is no external fuel filter on this model, it is attached to the fuel pump in the tank .

i would also suggest having it scanned to retrieve fault codes, to make sure it is not Fuel pressure sensor causing it oe a engine ignition related fault doing it,like a coils ,plugs , maf sensor ,ckp sensor ,but since it does it on low fuel , most likley fuel issue ,just to be sure and you are not throwing parts at it

You are very welcome :)

Isn't there access to the fuel pump under the rear seat on the driver's side??
Ford Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 6 months ago

reading the remove and replace notes on this one again

yes, remove the rear seat c,there should be an access cover and you use the tool to remove it

so no tank dropping on this one

it calls for 2.7 hours for labor hours, but still no tank drop ,from top ,that is good news for you
