The Fram filters were orange & black like the other bolters stated. It has a cover bolt that takes a 7/8 wrench although some use a big wing nut. The AC filter is yellow with black top. It takes a 5/8 wrench on the top bolt. The outlet behind the exhaust pipe with the tube going to the oil gauge is the pressure line. You may have to get a pipe T to hook up to it. It goes to the inlet on the side of the filter. It drains out from the bottom outlet & goes to the opening in front of the ex. pipe down near the bottom of the block.
