Changing The Fuel Filter

I wanted to change the fuel filter on my 10AE FC but I'm having a problem, removing the fuel like is a PAIN IN THE ***, I have tugged with a plier and it won't budge for the life of it. I can bearly grab it with a plier in the first place because of such little room.

Does anyone have any suggestion on how to get the damn thing off? Anything at all?

I cheat and replace the fuel line at the same time as the filter. That way, I can just cut a slit in the old line with a utility knife, and then pull the line off.

For fuel line I'm trying to keep, I normally have good success pushing the line off with a flat screwdriver. If I put the flat tip of the screwdriver against the edge of the line and push on that with my thumb (or pry), it will always eventually break free and come off.

Edit: I think pulling on the line creates the "chinese handcuff" effect, and makes it tighter. And, pliers tears it up.

Another Edit: If you want to save the line and can't get room to work at the filter, remove the line from the steel return line at the engine, and the supply line on the chassis. Then remove the line from the filter after you get the filter out of the car.

it's good to grab the line with pliers or something with teeth just to break it loose so it can spin where it is. After that you can attempt to pull the line off. I do this with water hoses as well. You have to break that sticky glu like feeling first.

It is best to go ahead and replace the hoses anyway and just cut them as buttsjim mentioned.

Even the flathead screwdrive technique isn't working, it's on there, hard.

You'll probably receive more replies describing other techniques. But, if it's on there really hard, then maybe that's an indicator that it's time to replace the line. For about $6, you can avoid the frustration and bloody knuckles.

if you can try to get into an oil change pit. this is where i changed mine during my last oil change. it makes it so much easier when you can just stand there and pull it off the line(watch out for the gas shooting into your eye) ...very painfull

Replace the fuel lines at the same time. Jus cut the old lines off. The reason the filter can't be removed is because the lines have hardened. They will be cracked internally and will likely leak after being disturbed. Use only fuel injection hose.
