Fuel Filter

Who is this guy?
I'm looking to replace my fuel filter today. On a previous thread, I read not to unscrew the nut from the lines, but from the filter itself because it can twist the line. I know to pull the fuel pump relay to get all the pressure out of the lines. What sizes are the nuts for the male and female attachments? Any other concerns to know about before replacing it. My filter already has the plastic clip on it so I don't need to swap it over.
 


Are both the male and female nuts the same size, or are they two different sizes? I'd assume the same size, but just checking.
 
Well, one big problem arose. When you look at the threads of the male coupler, you can see they're all rusted. I tried loosening the nut, but it wouldn't budge. I think the thread made its way all the way through into the filter nut. I didn't want to snap the the male end, thus becoming completely screwed. How can I go about loosening the hard line end without it busting off? I had no problem removing the bracket bolt and the quick disconnect side, but it was the hard line end that screwed me over. I was thinking of PB Blaster, good idea?
 
Like you said before, just hold the hard line and spin the filter off.

Rust is always going to be a problem. I know many people don't have one, but at work I like to tap the nut end on say the filter with an air hammer. Couple blaps and it can break the rust free without smashing the lines.
 


Well I can't spin the filter, because the bracket is also like rusted to the filter, so I can't spin it very much. I'd have to spin the coupler on the hard line. I couldn't even break it free with two crescent wrenches on each nut. I also don't have any air tools so I can't do your above posted method. The only good thing that came out of doing what I was able to accomplish, was that maybe a 1/4 cup of gas leaked out, total. I couldn't pull the FP relay (lol), so I used a rag and pushed in the Schrader valve on the fuel rail and released the pressure that way.
 
Or finally be over it, cut the line and buy a repair kit. What I did because it sprung a pinhole leak at the bend.
 


A couple of the lines down there are rusty. If a pinhole leak does appear, I'll JB Weld the b*tch shut haha.
