Thanks for the reminder. It took a while. I eventually ordered the kit from Mancini. The problem is most of the posts on differing forums are contradictory. Some claim that the adapter only fits a 318 LA and will NOT fit a 318 poly. In fact, that seemed to be the dominant opinion. Others were equally certain that the pressure differential between a spin on filter v. the original canister filter, wold cause the high pressure bypass valve to operate, resulting in no flow of oil to the spin on filter. After a great deal of research it became clear that based on the manufacture date my 318 poly did not have the bypass pressure valve. So I took a chance for the kit and it worked perfectly. I feel very confident you can all disregard the umpteen posts that claim a spin on filter adapter for a 318 will only fit an LA and not a poly. That is simply not true. I should point out that there were some post that agreed with this fact, but seem to be overwhelmed by others trying to make it a bit more complicated than it really is. Sorry for the delayed update.
