Art,
Orienting the adaptor is really quite easy. If you look at the picture that Bob posted on the first page, you see the adaptor and next to it, something that looks like a nipple/bushing (I don’t know what to call it.) The hole in the middle of the adaptor is not threaded. The nipple/bushing thing has a female ¾ inch (I think) end, and a male ¾ inch end, with a hexagonal (7/8 or 1 inch, can’t remember which) “nut” in the center for tightening.
You simply press the adaptor onto the filter block (It has double o-rings on the top.), then insert the female end of the nipple/bushing thing from underneath the adaptor, and screw it onto to the nipple of the
oil filter block, which is now coming through the center of the adaptor. Snug the nipple/bushing thing with a socket wrench and then attach the filter.
Theoretically, you could point the port end of the adaptor in any direction, but as I mentioned, it is a very tight fit. Since the adaptor is longer than it is wide and flat on the sides, it can really only be oriented toward the front.
I found it easier to attach the hoses to the adaptor first, and then attach the adaptor to the filter block. The swivel ends allow you to do that.
Fortunately, I did not have to adjust the length of hose, because I hate fooling with those braided stainless lines. Too many puncture wounds.
I did put teflon tape on the threads of the hose ends. They do however, come with o-rings.
Hope this helps.
