Technically it's something metric but 1/8th pipe works fine. ;D

Would the "something metric" be 10x1.0?  I'm trying to figure out which VDO pressure sender to buy, and they offer it in 1/8NPT and 10mmx1.0.  I know other vw engines use this metric size, so it wouldn't be a bad guess, but I don't want to get the wrong thing and have to deal with sending it back...

I know I should just get off my butt and carry it down to a parts store to have it measured, but I'm feeling lazy at the moment.

Correct it's a 10mm

I purchased the Mcnallyelectronics adapter that will have the 1/8 npt for my oil psi /oil temp guage

Gee-Bee

I thought about the McNally gauges; they're sooooo nice, but blue is the wrong color...  And they cost an arm and leg.  Thanks for chiming in.

This is for the turbo and oil flange, but someone said it was the same as the one on the head.

1/8 works fine, just wrap it with teflon, because the metric thread is not tapered, the SAE is a tapered thread.

head over to the parker store and get a M10x1.0 to 1/8NPT adapter, costs like $6 and then you are not chewing the threads up in case you need to do something else with it later.

1/8NPT will fit in M10x1.0, but it will ruin the threads making installing the proper m10 fitting close to impossible.

I ordered the M10-fitted pressure sender, so no ruined threads here!

The Mcnally stuff is very nice, Aircraft quality

All three look nice in my center console, and I found another company that makes speedo gauge decals in various colors to match with led lighting

Good luck Chris !
