I had a relocation kit on my 440 years ago. It was an adapter that had a plate that screwed on instead of the filter that I screwed 2 #10 AN fittings into. I then used Braided hose and ends to go to a dual filter adapter that I had mounted where the battery would normally go. It made it easy to change the filters without getting any oil spilled. If you can mount your 340 filter straight up and down, it'll save you the mess too. If you want it, do it.
