Installing an inline fuel filter
Has anyone here removed the hard rubber fuel line next to the upper plenum on the passanger side to install an inline fuel filter? I tried to twist it off lightly but it seems like it's glued to the metal pipe and I didn't want to accidently damage the pipe.
Can I just cut the metal pipe and reconnect it with my own rubber line and inline fuel filter? It seems like I would need the end of the pipe for that high rise to keep the hose clamped on and prevent it from slipping off.

I wouldn't be messing around with the high pressure fuel lines without carefully reading the service manual for the proper way to disconnect the fittings. Things can get really ugly when fuel starts splashing around the engine compartment while you cruising down the interstate.
Why do you think you need a filter? There's one built into the pump.

that dirt is going to be prevented by installing another fuel filter - a fuel filter can only trap dirt in the fuel lines, and if you had that much in your fuel lines, your car wouldn't be operational

I found out the fuel line is hard plastic covered in rubber, so I cant clamp on the plastic with a rubber hose. The only part that is actually metal is the Y line that is part of the fuel rails.
I'm just going to try some other injectors to see if that fixes the lean problem.

Running better fuel and cleaning the tank would probably be a better idea. If you really want another fuel filter, I'd suggest putting it as close to the pump as possible so that when all the stuff gums up your lines/pump, there's not a whole lot to replace.

The fuel filter has nothing to do with the engine running lean, and replacing the injectors probably won't help either. The ECU will keep the injectors open long enough to get the mixture correct based on the feedback from the various sensors.
What makes you think the engine is running lean? Are you getting a CEL or any codes?
The most likely causes for the engine running lean (if it's really doing that) would be the mass flow sensor or the O2 sensors.

Need scanner and read datasteam's fuel trim adaptation. I just bought a car with a cat code, i checked the fuel trim and its maxing out the values rich because O2 sensor is seeing all the oxygen from the NOx the cat isnt converting. It will only set codes once it maxes out fuel adaption limits.
Sometimes cars get stuck at the 9999 value and code sets at 10000. Good tech can read the scanners mode 6 data to see codes before they set.
If you can do an emissions test you can plug in the number's at
