My engine builder put a -4 45 deg nipple on the acc case for oil pressure. It is at a bad angle, pointed down and outwards. I think I really want a 90 deg pointing to the left and up, away from the right mag. Is it possible to remove this once the engine is hung? I know it will at least be hard, as it is very close to the dynafocal mount, but is it even possible? I have nimble hands and a mastery of bad language I just don't know if there is enough space. Anybody removed and reinstalled one of those with the engine installed?
