One of my filter tops stops tightly in a certain place so that the wrench will not fit. The space between the 12'oclock position of the lid in this pic and the pipe coming up from the pump is too tight for the end of the wrench to fit in.
What is the remedy for this? Is there a type of wrench that will fit? Can I use some teflon tape to build up the threads so the lid tightens at the 10 o'clock position instead of where it does now?
