Changed plenty of filters over the years and never had an issue and I change mine every year. Clean the top of the fuel filter housing, where the top and body seal and around the fuel pipes in-situ. Pop a socket over (I've used 12 point BUT try and use 6 Point...less issues!).
Push down to compress the wave spring, while turning, just to break the seal and facilitate the removal of the pipes (maybe 20 degrees). When removing the pipes, be ready with tissue as it will leak a fair bit. The pipe which goes into the HP pump, cover with a clean bag (or thumb off a plastic glove) and seal with a rubber band.
Keep some tissue over the pipe outlets on the filter lid, fuel will continue to spurt out. When removing the cap, be ready for a LOT of diesel to come out everywhere. Ideally have a strong bag without holes beside the fuel filter housing.
Drain the old diesel out or soak up with loads of tissues / rags. New seal, new filter (only fits in a specific way, there's a tab!) and re-do it back up. Make sure you prime your car before starting to bleed as much air out as possible (turn key to "on" position but do not engage starter. Turn off. Repeat. I do it three times..I might have OCD)
Swapping out for a new housing seems excessive and expensive.
