I soaked it in WD40 and went at it with a wrench and hammer for a good 30 mins. I can't seem to get the fuel line to budge. I don't want to heat it cause its a fuel line....

What methods did you guys use to loosen yours?

 

are you stripping it?

if not, man up and get it done

 

pull up your dress, strap on a pair, and give it hell

 

it would help to purchase a line wrench, cuz when theyre that tight, a normal open end wrench has a tendency to strip it out....once you get a line wrench, give it everything you got and expect a wonderful new slice on your hand when it gives....hopefully youre not a hand model.

 

I get it from below with a special tubing crows foot on a very long 3/8 inch extension. Sometimes with a soft 3/8s impact wrench gets it loose. It is very tight from the factory on the Accord. If it's a Civic, WD40 is not the best rust dissolving penetrant, try PB Blaster.

 

Heat it with a blow torch

Sorry, those things can be a bitch

 

impact wrench would take it off quick.

i dont see how you cant take it off by hand.

maybe use a breaker bar to help?

 

use a bigger wrench. pb blaster works better than wd-40. mine was a pain too.

 

Just don't get cheap@$$ flare nut wrenches like the ones I have. Those damn things flex so much they're more likely to round off a hard line fitting than my open-ended Craftsman wrenches do.
