Well, spraying the PB Blaster all week helped as I got the back fuel line fitting loose easily, but I couldn't get a flare wrench on the front fuel line inlet. So I decided to remove that front section of fuel line with the filter to separate them in the vise. Wow, I had to take quite a few fuel line clamp bolts out, the filter bolts out, the parking brake cable bolt out before I could remove the fuel line/filter. Once I got them in the vise the front fuel line fitting popped loose pretty easy as well. Got it all back together and it feels more responsive. Some nasty stuff came out of the old filter so I'm sure it was blocking some fuel pressure.

I don't know what you have in the gas in CO, but I had gas all over me because I didn't take the cap off and the tank pressure kept forcing gas out. Once I relieved the pressure it stopped. You shouldn't be getting any chemical burns from gasoline so your gas must be messed up or something.
