E-Ticket said:BTW, how is your Pro-FILL filter sock held on to the fuel pump. Did you remove, and re-install, the circlip over the mounting stud?
You remove the circlip to remove the stock filter, but you do not reinstall it. The Profill filter is just a pressure fit, and then the way it sits in the black plastic housing prevents it from falling off. But if the plastic box popped open, the filter could fall off.
It might be possible to install a circlip, but it would be challenging due to the shape of the filter. No way to put serious pressure on the clip.
