I own the truck listed above extended cab three door automatic, flex fuel. The eighth number of the VIN# (5) * trying to be as thorough as possible in my description*

Here's the question:

When I look up the part (fuel filter) online, eBay, AutoZone, etc. It shows two kinds for exactly the same engine with exactly the same description. It shows one that has a single line at one end and a single line at the other [just like the one in your YouTube video]. Now for the other, it shows 2 lines going in one end and one line out of the other end. I've seen this one installed in YouTube videos as well. Which one is it? I am so confused.

I am a double below knee amputee so getting down on the ground and getting back up is extremely difficult so I cannot just go under and look at it, I need the right part sent to me so I can do it all in one shot.

Can you please help me figure out which one I need?

The reason for the difference is which engine you have. The 2.2 came as a flex fuel or a non-flex version. The two-port fuel filter is for the non-flex engine while the three-port version is for the flex fuel version and has the pressure regulator in it. So, if your truck has the flex fuel option you need the filter in the first picture that has three quick release fittings. If it isn't the flex fuel version then it uses the second design, it has one quick connect and one threaded coupler. Both are mounted in the same place. You will need to clean out the retainer clip area to get it to the point they release easily. You will also need to release the fuel pressure before removing either one. To do that the easy way is to full the fuel pump fuse or relay and then try to start it until it won't try to start. Then the pressure should be out of the line.

Hi Steve, I do have another question. Okay, here we go.
I have replaced all of this with brand new parts: fuel pump, fuel filter, throttle position sensor, air flow sensor (not sure if that's the exact name but it's right near the T.P.S.), All 4 injectors, spark plugs, spark plugs, spark plugs, spark plug wires. I also blew out every drop of fuel in the system (lines, etc. ), Fuel tank. Cleaned it all out and put fresh clean fuel in it. Flushed out old engine oil and the engine. Changed filter put new oil in it. Flushed the radiator and engine with coolant flush then completely drained radiator put 2 gallons of coolant and 1 gallon of water in it. Replaced the thermostat and radiator cap.
I mean truly did it up because I want it to run smooth as silk and last me.
Here's the issue/issues.
It is hard to start. I either got to pump gas or hold it to the floor then after a bit it will finally start. For a couple days it seemed to idle way to low because it would flood out the engine and dump gas into the exhaust and smoke like crazy. Then start skipping and jumping and finally stall out.
I wiggled the throttle cable, and it did seem kind of frozen. I also just massaged the throttle wheel so now it runs great just as quite and smooth as silk no problems there. But it still is a task to start.
Any ideas? I am sorry this is so long, but I feel it's best to tell you everything I did to it.

Thank you

Try this test: turn the key on, wait a couple seconds turn it off and repeat two times. Now try to start it, any change? Yes - check the pump relay to see if it is cycling to prime the system. No - Are the injectors sticking and flooding the cylinders?
