So I have 3 injectors on the pass side allowing air to pass horrible during ICP leak test. I pulled the rail and put in Alliant Nipple cup seals. No help. I pulled the rail again and put in new Alliant seals on all 4 injectors top O rings that the nipple cup plugs into. Same result. Of course with the rail on you cannot see much but I cant see how they could be leaking at the top with new seals. Is it possible they are all leaking past the spool valves that bad?
