Electric water pump WITH heat?
Thank you sir!
Again, if anybody knows if what line is the inlet or outlet on the heater box, don't be shy lol
Feed is 5/8 - so connect to the bottom plug (which is on the driver's side)
Return 3/4 - so connect to the top plug (which is the passenger side)
Seem right?
I think since I can find a 1" NPT to 5/8" barb, I'm going to take a 1"NPT to 3/4" barb and just turn down the OD 1/8th to get it to 5/8"
See how that seals.

I called and he said it was a 9/16" "O-ring thread"...which can't be correct, because I'm getting around 0.910 for a minor thread pitch. I'll have to take it in tomorrow and throw some thread gages on it.
But I don't believe it is a NPT, he said it wasn't, but I've never heard of a "o-ring thread"....is that just a straight thread?
I'm going to take my 1" NPT fitting into the shop, I'm going to look into what makes "O-ring" or "AN" threads different than the norm. I might just turn my fitting down and turn some threads onto it.
