Hello all. hope someone here can help me. I am going to replace the electric oil pressure gauge on my 1982 Toyota 2.4 p/u. I have already purchased the new manual gauge but I need an adapter to go from the metric size (I think it's 10) to the NPT threads. Any ideas where I can get this? Any help appreciated, Rickyota

 

have you tried a parts store ?

brass unions are avaliable ...

Yeah, thanks . I have found NPT to metric but seems like the metric to npt is unusual ;-). Anyway I'll figger somethin' out. Arkie ingenuity will get 'er done.

 

I put an aftermarket gauge in my '88 with a 22R. If I remember correctly, Toyota used a different type of pipe thread. It was something like BPT (British Pipe Thread), which is different than NPT and metric bolt threads. I cannot remember exactly, but I think I got the NPT fitting to thread and was just real careful not to overtighten it.

 

Summit Racing has the adapter you need, It is like $4.00. I dont have the part no on me right now.

supernerd is right. it is BSPT it is really similar to 1/8" pipe but has one thread count difference per inch

 

Thanks everyone! We got 'er done. Just as 'The Supernerd' said. It worked. Having fun so far! ;-)
