90 deg adapter torque specs

50ft lbs is spec, but the spec sounds over the top, just like the torque specs in some manuals on a rocker shaft that frequently break bolts.

Run 30ft lbs, see if it seals. Filters seal by hand with a good grip and elbow grease. 35 is what the pump to block two bolts are at. Factory rod to cap stud nuts are 45, if that gives you any inclination as to how tight it really needs to be.
