How do i find the fuel filter located on a 2004 gmc yukon xl?

SOURCE: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

SOURCE: where are the oxygen sensors located?

There will be one located before, and one located after the catalytic converter for each exhaust that you have

Code po449 is the canister vent valve solenoid error.This is a common problem with these valves because they are under the truck in the rear by the spare tire and they get all the dirt and water and snow,if you live in an area where you get snow.You will find it on the canister under the vehicle by the spare tire.

SOURCE: HOW DO I CHANGE THE FUEL FILTER ON MY 2002 GMC

First - Safety is always the key to working with fuel:
1) Remove from the area of work anything that could ignite the fuel, 'High intensity shop lights, no smoking'
2) Work with a flash light or directional battery operated light if its dark.

Two tools to have in my opinion -
1) Pliers
2) Needle nose

1st - use the pliers to spin/break the hose end loose over the In and out flang of the fuel filter.

2nd - If you have a needle nose pliers which have a very narrow nose end.
Place the nose end all the way at the hose end that's over the fuel filter's intake/output flange.
You then can leverage the hose off by forcing the body of the needle nose up against the body of the filter.
Just like a teeter totter where the body of the filter becomes the /\ fulcrum of the teeter totter.
Hope this makes sense?

Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.
