Insane, I was about to post the exact same question. Just bought a Nexus set and need a place for either 1/8" npt or 1/4" npt for oil pressure.I am trying to add an oil pressure guage and don't know the best place to tap the sender to. Normally you tap where the oil filter and stock sender are, but there is no way I can see to tap into.
Thanks for the help.
Either that or a sandwich plate. the IS300 bolt would be the easiest, we use those to tap for oil feed on NA-T setups.
