Regarding picture of RRE turbo oil supply line shown on following How To post "Best Place for Oil Gauge":

Does anybody know the size of the BSPT where turbo is attached? I would like to use adapters on that in order to put on oil pressure gauge unless you can suggest a better spot or way. One post said 91-94 DSM ofh has two 1/8" ports on it that would work nicely but that would be quite a bit more costly.

It's 1/8" BSP but just use 1/8" NST with thread locker. I used a grease gun flexible hose that was 1/8" npt and it seals just fine. just don't over tighten it.

All the sensors are 1/8" npt any way.
