I'm looking for a T-piece, to fit an oil gauge to my Zetec, while continuing the use of the oil pressure warning light.
Now I have found several shops which offer T-pieces, but my oil gauge has a thread of 3/8 NPT, and all the T-pieces have either 1/8 NPT or M10x1.
I have a regular VDO oil gauge, so why can't I find a suitable T-piece? Or does 3/8 NPT fit M10x1?

try Burtons
http://www.burtonpower.com
they seem to have most stuff like this. I think I bought my tee piece from them. Like you I have a VDO gauge and sender, I can't remember the
thread sizes though.
or here: www.lma-group.com/motorsport/Products/Gauge_Fitting_Parts/gauge_fitting_parts.html
3/8" nptf is not the same as M10 x 1.0
I was recently looking for some M10 x 1 bolts to fasten prop to rear diff flange. Non of the imperial similar sizes were close enough. I had to buy
proper bolts from Ford.
Im fitting DD2 to my car (Pinto engine). Oil pressure warning light sender replaces std ford sender. I have to get an adaptor to replace the oil
gallery plug to fit the oil temperature sender so i can get an oil temp feed to the gauge. Is this an alternative idea? The new oil pressure sender
has two connections - one for the pressure warning light and the other for the pressure gauge. It is a neat solution and i think they are available
for sale seperately on ETB website.

Aha, thanks for the response. You seem to know about threads alright.
But.... the package of my sender says it's 3/8-27 NPT. Could you tell me if this fits either 1/8" NPT or M10x1?
(hmmm, I must say I find this pretty confusing.....)
Cheers,
Marcel

Hmmm, it's even more complicated than I thought......
To make things even more complicated; in the package there were also three adapters. According to the package it was supposed to be just one:
3/8"-18NPT to 1/2"-14NPT.
All three adapters in the package have a different outer diameter/thread. But they all fit the sender perfectly with the inner thread! Sooooo, does
that mean the sender is 3/8"-18 NPT?!?
Is there any way I can determine the size without having a thread caliper thingy?
If the outer diameter of the sender is about 5/8" then it could easily be 3/8-18NPT
you're quite right, have PM'd Mave with the error!
I have bodged these together before, but with brass fittings...............Doh!
Sorry, my error! (I hate giving wrong info!)
Only answer is an adaptor.......
Just read your post again, here's the correct answer!
No it won't fit, you need an adaptor, part number FBM2138 from Think Automotive in London, which is a male to female adaptor, 3/8nptf to 1/8
nptf. £4.11 each.

Thanks.
I've send an email to Think Automotive and am waiting eagerly for their response.
{edit}:
According to Think Automotive, the outer diameter of 1/8 - 27NPT is 13/32" and the outer diameter of 3/8 - 18NPT is 11/16".
Also note that the 27NPT is indeed for the 1/8. Soooo, combining all this info, the only conclusion I can draw, is that Alan is right, and that the
manual has a misprint. I must have the 1/8-27 NPT. And can use a normal T-piece!
Thanks again, and a big thank you for Think Automotive for the rapid response!
