thanks bonzo :)

Well I looked

Guess what, it snapped off :D :D

Not all is lost though, I am almost certain sure that Ford use a 1/8th NPT taper thread for temp senders ( More or less an industry standard )
I guess that's why most el-cheapo tap & die sets have a 1/8th NTP tap in them ;)

Here's an ebay linky, not going to break the bank.

Ford Temp Sender

Gosh that's cheap, I tried my local motor factor and they want £10 for one! So never having done a drill & tap before, what size should I drill the hole to for this before I try tapping it? (I've only got metric drill bits as well...)

According to my little Red book ( Osbourne cutting tool guide ) the tapping drill size for 1/8" NTP is 8.4mm :)

An 8.5mm drill bit will most likely do the job if it is a decent quality one ;)

Is 1/8 npt the same as 1/8 npt27? I checked my tap & die set and I've only got metric ones so I'm going to need to buy one and considering this one http://www.ebay.co.uk/itm/24-Piece-U...em2 7b6c747b3

Hi

Yes according to my Red book a 1//8th NPT thread has 27 teeth per inch :)

I have 2 or 3 of those, you are more than welcome to have a lend of 1 if you don't want to spend a pile of dosh on a tap set that might never see use again.

Also got a good stock of 8.4mm drill bits, quite welcome to have a lend of one at the same time.

Hope that is some help to you :)

I might take you up on that bonzo, I'm going to check with the neighbor tomorrow in case he has one but if he doesn't a lend of one would be great :) Already had to spend a small fortune on coolant hoses so any money saved is good!

You will be most welcome if your neighbour is unable to help :)

Nope the neighbor didn't have one but I'm considering buying a set anyhow as I'll need one for the seat belts too and it's probly a handy thing to have for future use. Do you know what thread the seatbelt mounts is supposed to have? I think it was something like 5/16 but there seems to be more than one thread type when I look at these two:

Hi

Yes, the seatbelt bots are 7/16ths UNF/NF

If you are creating a new thead for those the tapping drill size is 9.9mm.

The exact reason I keep all of my imperial stuff here, tis surprising how often I have a use for one of em
