Fuel filter replacement ?
I am going to be putting in new injectors from Jon from FIC in my 95 with 69000 miles, not sure how old the filter is I really don't want to change it because of all the stories i have heard. Is it really that bad of a job ? what should I do,don't want to mess up new the injectors .

It's not that bad. I searched tech for step by step and went from there. I disconnected one hose from underneath and pulled it up through the engine comp. Just make sure to pull the fuse first. also have a container ready for gas from the hoses.

The fuel filter can be a pain to access and remove. There may be a small heat shield to remove to get to the filter.
To keep the gas spillage to a minimum, there are a few tricks. The fuel rail on the passenger side has a Schraeder valve that will allow you to release fuel pressure at the rail. You can also pull the fuel pump fuse and start the engine and let it idle until it dies. It's a good idea to raise the front of the car as high as you safely can so that gravity won't cause gas to drain from the tank. Have as little gas in the tank as possible.
You will need flare wrenches to remove the front and rear parts of the fuel line. Don't try open-end wrenches or Crescent wrenches; you don't want to round off the nuts.
If you don't want to mess with doing it yourself, take it to a reputable shop and have them change it before you do the injector swap.

I don't know where they are on a 95 but on my 90 the biggest issue was getting under the care to get to it. After that fiasco it went pretty smoothl. I agree with relieving the pressure as mush as possible and have something ready to collect the fuel that does drain.

For safety's sake, be sure and disconnect your battery after you've removed the fuel pump fuse, started the engine, and allowed the fuel to run out of the line.
It's all too easy to accidentally create a spark with your tool and the starter solenoid, knock sensor shields, or other metal components while you're underneath there.

We lifted mine....removed shield. Took off line on bottom. Put socket on the bottom of filter with extensions and I held nut on the line on top with a wrench while a friend turned it and it came right out. Wasn't bad at all.

I'll admit this one wasn't as bad an experience as I'd thought it would be. While I don't know if the LT1 cars have a different fuel filter, on my '90 the only real pain was that even with pulling the fuse, and cranking the engine you're still gonna end up in a puddle of gas 
it's a little fiddly, but any novice with a jack and some hand tools can do it and feel like a hero. My C4 had a horrible problem where it wouldn't want to start from time to time, it would crank but just not fire. Changing the 20 year old fuel filter solved that problem.

Don't intend to beat a dead horse but, Turn off the pilot light to your water heater, and don't use and incancescent drop light, if the gas drips on it, kaboom. I had to disconnect my fuel pump to stop the siphon.

I did my 86 by myself from under the car. It wasn't a big deal at all. Just need something to catch the fuel...other than that, I just connected the other one as fast as possible and didn't really lose much anyways.
