SW heat gauge

[P.J.]

Thanks John
the dia. of the pipe thread is 830 thousands of an inch at the cylinder head head and it is 14 threads per inch.
If necessary I can step it up from 3/8 pipe to 1/2 pipe if it is the correct sending unit for the gauge.
Let me know what you want for it
Thanks

Peter, the 1/2" variety is available from

You need part number 90-975. Don't worry about it saying 100-240 degrees, because the Deluxe gauges just leave off the number 60 down at the bottom of the gauge. I didn't know what size hole you had, but I'd rather see you get the correct sender instead of having to use an adapter. Just glad I could help out.

I have a bunch of NOS ones. The part numbers are 362AA, 362AH, and 363E. Let me know what you need.

He needs a 362-AH. They're brass and brass won't weld itself to an aluminum intake.

What is the difference between the 2? They look the same externally except one looks to have a steel body and the other is brass.

The difference in the numbers is brass vs. steel body. The boat versions are brass, but steel welds it self to aluminum through corrosion, so I wouldn't use the steel ones for that reason. If you have a cast iron intake it wouldn't matter though.
