Oh poo, oil sender doesn't fit
norfolkluego - 6/4/10 at 06:36 PM

Finally took out the the oil pressure switch and now my new oil pressure sender doesn't fit (see piccy, new one to the left). The new one is 1/8 NPT, can I get an adaptor to make it fit the Zetec or do I need another one?

Incidentally before anyone asks, the letter from 'Vaseline Dept 827' is nothing to do with me, it's the wife and some sort of miracle face cream Rescued attachment Oilsender1.jpg

I would laugh, but it aint funny....

I just had exactly the same prob with my Pinto presure switch.
I managed to sorce an adapter at my local gas/plumming center.
10mm to 1/4NPT

What threads the old one ? They went metric on the black tops.

I have an m14 to 1/8npt adapter you can have for what I paid.

No idea what size the old one is, standard blacktop size I assume. Doddy, don't think I've got any chance of fitting a tee piece, think it would foul the engine mount and the filter housing Rescued attachment Senderhole.jpg

Just had a bit of a fiddle and the biggest nut I can find is an M12 and it's bigger than that, so Wasa I think you're right with M14. I'll take you up on your offer of the adaptor, just let me know the price.

I think they are 1/4NPT... but not sure! Most older ford engines are anyway.

doddy - 6/4/10 at 07:33 PM

mine was the same size as my pinto then i put a 45% angle extension on it to clear the block

flak monkey - 6/4/10 at 07:43 PM

Pinto is definately 1/4NPT.

Try ETB instruments gave me a top service when I needed adaptor for my k series engine and postage costs resonable.

ETB even told me what thread I needed.

You may not need a T-piece.

The Zetec silvertop has 2 tapped holes in the block, so on mine I fitted the VDO sender and in the other the standard pressure switch.
The second hole is fitted with a plug.

Looks like you need a 1/4NPT to 1/8NPT adaptor - something like this:

I had the same when fitting my pressure gauge.
