8BA water temp,sender thread size
 

Hi guys I,m looking to fit as temporary till I can sort out the original a remote temp,gauge on my 8BA,the only snag is the remote I,m fitting has come off a vehicle fitted with a Ford V8pilot engine and the bulb/sender fitting is different and wont screw into the 8BA,i need to make an adapter or maybe cut a thread on the bulb( I don't really want to cut the head hole ) and need to know the thread size to cut, anybody know the thread size of the hole in the head of my 8BA,the engine has been totally rebuilt and is ready for its first proper run and I need to know whats going on with the engine . many thanks Jim.

The 8BA temperature sender thread size is 3/8" NPT (national pipe thread).

Re: 8BA water temp,sender thread size
 

Speedway has them they are called water temperature adapters. The part number is 182-2370, thats adaptes bulb to 3/8 NPT.

Might check NAPA for mechanical temp senders. They come with adaptors that fit right in. Put two (one in each head) in mine a coulple of years ago.

If you have acess to the adapter used in MGB, MGA for the Smiths temp gauge bulb it would be worth trying

Thanks all ,on u.k ebay yesterday I found an adaptor,male 3/8 npt to female 3/8 bsp
which according to our pilot v8 man over here is the fitting into a pilot head so hopefully ....job done ...cheers Jim.

Pilot motors have a 5/8UNF thread in the heads for the water temp senders. USA type motors tend to have 3/8 NPT as stated.

O.k Mart ,I havnt received the unit by post yet ,I was told by Chris the pilot owner the size ,I,v got a 5/8 unf tap if all else fails I will use it on the head but will see if I can get another connector of the correct size first, thanks Jim.

Anyone know how to get 1936 Ford Coupe original temp guage with 1/2 male NPT into an 8BA head with 3/8 NPT?
thanks much

bndouglass: You could cut and solder two brass fittings together similiar to what is shown. One end would have the ID gauge size thread size and the other end would have the OD head size thread size. Shown are early heads on an 8BA.
