Hi. Hog thought you might have.... it's the obvious thing to do.
I've only change the filter once so no problems, but just thinking if I had to do it I would find two new glands that fitted my new filter plus some flexi petrol pipe or from a scrap car and with some steel pipe still attached and after cutting removing the damaged ends fit the replacement glands/pipe with a bit of petrol pipe as a joining sleave plus clips to to form a joint.
Just a thought
