I am trying to replace the fuel pump of my Volvo V70 I 2.4 (106kW, 1998, manual), but can't remove the fuel line connector from the pump assembly. The return line seperated easily, but the other one won't budge.
I've pulled down the lower sleeve towards the pump and then tugged it upwards, which worked perfectly for the other one. This one is thoroughly stuck. I've already tried to apply some WD40, without success. I've also tried to pull it out with pliers with as much force as I dared, but to no avail.
How can I remove it?
