Disconnecting fuel line from filter, why does volvo use fuel connectors from hell ? (And how to disconnect them ?)

Hi,

I have a XC70 03 with leaking rusted fuel filter

Got a new filter, tried to replace it but it didn't work as I'd hoped.

On the fuel line connectors, there are gray tabs that you're presumably supposed to press to release the hose.

I pressed them, the hose turns but it doesn't release. Got in a better position, pushed as hard as I could with my fingers, I cut myself a little, push-pull-twist-yank-push-pull and so on, it just won't let go

I squirted a bunch of penetrant lubrication fluid into the hose connectors

I tried squeezing it with the vice grip, but that doesn't squeeze the tabs, it just holds on to the connector's body

I tried the smaller vice grip but same thing

I tried wrapping zip ties around it and squeezing the heads of the zip ties onto the gray tabs

But the awkward position, trying to juggle the zip ties, the vice grips and everything was just too much !

So I had the idea to put tape around the connector

And then stick the cut heads of the zip ties in place

Now I've got them good on there !

push-pull-twist-yank-push-pull again, but it won't budge, it does turn just fine but it won't come out ! Yes, I tried pushing hard !

The tabs are pushed in permanently now, I wonder if that's going to be an ever bigger problem ?

I went on youtube and the forums, looking for the trick maybe ?

I see on ebay, there are special pliers that might do it ?

I tried the 5/16" tool

I tried the filter inlet side, that's the leaking side, it broke off immediately

And I've got another tool to help me pry the connector from the filter

Well, I'm stuck, I also tried heating the line with a hair dryer, but no effect

I ordered the two fuel line disconnect tools off ebay, I hope they will arrive before the end of next week !

Is there any way to buy replacement hose end connectors, so I could just cut off the lines and push in new connectors ?

I really really really don't want to change the lines, especially not the line that goes to the fuel pump !

I've seen that you have to cut a hole in the floor or drop the subframe to get at the fuel pump so .
