stuck fuel line fittings

[merc2dogs]

Anyone have a trick to remove stuck fuel line fittings?
They're the basic quick release type, slide the tool in and pull apart is how they are supposed to work...

Have three that are completely stuck in place. I am using the right tool for the job, but I'm unable to get them loose.

One (on regulator) I pulled the spring out of and I still couldn't get it off, so I ended up cutting the line and clamping it.
I've been trying to change the fuel filter, and spent over two hours prying, pulling, pushing etc. (while laying in a snowbank!) and can't get either one of them free.
Since these are on the pressure side, I don't think cut and clamp is a good option.

Any help is really appreciated.

They were all soaked in PB blaster before starting on them, and they're currently soaking now.

make sure they can spin in the line. if they don't spin in the line, they aren't coming off. beyond that, sounds like you've already tried my two standard suggestions of

PB Blaster, and

Pull harder.

I've found filters that needed two people to get them out before, one holding the line and the tool, one hanging all his weight off the filter to get it out.

If you're in the rust belt the connections get clogged with rust making them next to impossible to disconnect. Just cut the line and clamp the hose back on, it's only 60 pounds maximum, nothing a half assed clamp won't hold. If you can create a small lip on the end of the metal pipe with a flaring tool, so much the better.

start spinning/twisting the lines to break the o-ring free. same process as getting a stuck hose off. i deal with this stuff allllllllll the time.. sometimes in extremely cramped spaces

like said above break the line and connect a good sturdy hose ive seen it tons of times at my aunts shop the guys try to remove the filter and it never fails the line almost always breaks and then they have to replace the line with more metal line but a simple hose has got to be the most simplest idea ive heard to fix that problem

cut them if they wont come off and if they do eventually come off they wont go back on again. i struggled for about an hour to get mine off and then it wouldnt go back on because it was all rusty

Thanks all, Cut and clamp sounds like the new plan.
Never ran into them that were that hard to bust loose, had to pull and cuss a bit, but never had any that made me walk away from them.

Thanks again!
