How to change a fuel filter on a 83 caprice classic 305?

If I'm looking right it seems to be on the carbuerator itself, problem is how do I change it? What size wrench do I need and what's the process. I tried to remove it but it began twisting the fuel line. It's a Rochester quadrajet carb. I know someone out there knows, thanks in advance%26amp;

you have to take a wrench and hold the metal housing that the line goes into, and take a small wrench to loosen the line. may have to loosen tighten, loosen tighten to free up the threads. if its not budging soak it with some penatrating oil. its not metric wrench sizes.

You will need a 1 inch wrench to back up the filter housing and a 5/8 inch flare nut wrench for the line. Hold the filter housing still while you remove the line with the line wrench, then remove the filter housing with the 1 inch wrench. Be careful to take care of the threads on the Q-jet and don't twist the line. Make sure the spring goes in under the filter and the white nylon ring stays on the housing. Don't over torque the housing. The filter is a few bucks.
your suppose to take the line off first then just use a cresent wrench or a box end wrench to unscrew it. i changed several of them when i had a 78 pontiac.
