temp switch
 

the temp switch that is in the head. i have the one off my 305 going onto my 400 and the hole is bigger on the 400 head so it wont fit the senser. is there a adapter or a bigger temp switch i use?



also. i need a plug the same size for the other head.


thanks:metal:

Yes you can use an adapter, you must have an aftermarket gauge do you . I thought all temp sending units were the same size until you got into the newer stuff

It's out of a 84 305 going into a 72 400 so the years are apart. And where could i get a adaptor? Summit?

anyone else?

The temp. sending units are both pipe thread one id 3/8's NPT and the 400 uses 1/2 NPT. You can go to any store that carries plumbing stuff and get an adapter to make it work. Here is what to look for

yup thats what i got. it was like 2.50

use that white piping tape one the threads right?

Re: temp switch
 

look for some high temp stuff to seal the threads

Too late it's all already in. Along with other parts with white tape
