DO NOT restrict the oil flow to the filter or you will be looking for a new engine in very short order!!! Also, you need to be sure that the whole oil filter system is filled with oil before you attempt to start the engine. The engine would be oil starved for the time period it takes to pump the oil through all of the lines and fill the filter. You need to pressure force the oil through the lines and filter and back to the engine prior to even thinking about an engine start.

A by-pass filter uses a restrictor to bleed off a portion of the oil to go through the filter and then back to the oil pan. The 95% modification passes almost all of the oil through the filter and then back to the main oil galley in the engine. Except for the small amount going to the rear main, all of the oil must pass through the filter and the passages and fitting have to have the least restriction possible to assure good oil flow.

Also be sure the in and out on the filter is connected properly! I believe it was O'Ron (a very knowledgeable and experienced engine builder) that made this mistake and trashed an engine. You really, really need to understand how the modified oil system works and double and triple check everything when using it.

During the 95% modification there should have be a block placed in the horizonal passage in the port between the oil pump and the main oil galley. This is what diverts the oil through the filter.
