I have read over the entire Accusump site. I've also read all the posts on this site on the topic, prod forums and some others. I have yet to find a specific answer on the best place to plumb it on a 13b. Doesn't look like many IT cars run one, also somewhat of a like it or hate it device. My purpose is for pre-oil and security. I don't have any pressure problems. I'm going to plumb mine with a check valve and tee into the oil cooler return line unless someone chimes in with a better solution.
