Heater tube assembly

[Steves LX]

Does anyone know what size the threads are on the heater tube assembly that screws down into the intake on the fox body's. Not sure yet but I think mine may be cross threaded. I put thread sealent onit when I installed it the other night but I have coolant coming up around the threads. I hope I dont have to tap the intake hole. If so I need the size and where would I get a tap for that?

Whatever it is, it should be NPT threads...

I have a few laying around we could check the threads on if you can come up with a thread gauge.

I have about 6 complete upper and lower intakes in the back of my truck righ now.And I have some fittings that thread into the lower for the coolant tube that have a barb fitting on the other end.Just some things I was going to play with.If I can find them,Ill get the size for ya.They should be at the house.
Ill give you a ring either tonight or tomorrow when I get the size.If anything I can run down to Aeroquip and he can tell me the size.

I hooked him up last night. She runs now :D

Was it stripped?

Well.. the end had some booger'd up threads, which booger'd up the first couple threads in the intake. He got a tap and chased the intake threads... but his heater tube was done for.

That heater tube is a great idea,just horrible design.
