Oil Pressure sender threading?

[JustAnotherVictim]

Does anyone know what the threading for the Oil Pressure sender is? I'm working on a 1/2 na-t and I'm sorting out the turbo drain issues. I need to find fittings to make the line for the drain big enough to accomodate the oil flow.
Thanks

The pressure sender is 1/8th BSP.

Actually... I have two blocks here with two different thread sizes.

I suppose it's possible that one was retapped...

What are the 2 threads Grim?

All of the 7M's I've had through here have been 1/8 bsp in each of the 3 pressure ports.

I end up tapping the middle one to 1/8 NPT so I can use my AN fitting.

I have a set of Braided Stainless steel oil lines for a CT-26. They are leftover from my 1/2 NA-T build, the return line has a slight indentation but it should be fine. I will sell them for $60.00 shipped if you are interested.

I've no idea what the two threads are, actually. I do, however, know that the oil pressure sender that came on my first block will not thread into the hole on my second one, as it is too large. It looks like a stock sensor, but who knows?

Were they close in size just wouldn't thread in or totally different sizes?

STOCK oil presure sendder without a doubt is 1/8" BSPT.

If it is larger they retaped it to 1/4" BSPT but more than likely to NPT.

They were close. One is just a bit bigger - as though they used one tap size larger in diameter.

Do you have some pics and what's the line diameter?
I think it was one of your threads I saw this method on SF

Grim: It jumps up from 1/8" bsp to 1/4" bsp and it's a pretty big step in diameters!

1/8" 0.383
1/4" 0.518

No, mine was more like 1/8" to 5/32", nothing that big.
