I just stand there like a kid in a candy store watching all the action.

It's currently off the engine and drying so I can put another coat of paint on it, after washing it out to make sure I don't get any metal shavings inside the engine. That wouldn't be good!
That's smart . I wish I had done that on my Suburban...

Re: Knomadd '71 SWB C-10

Great idea and I think I'm going to steal it if you don't mind. Did the fittings come from vintage air? Do you have a part number?

Thanks Rob. I wasn't going to do it, but I couldn't get the #12 hose to fit over the larger fitting and I really didn't want to run standard rubber heater hose. My other concern was when I have to replace this water pump, I'll have to do it again. "What if it happens on the road?" Well, the water pump should last me 100,000 miles or more, so it shouldn't be a problem. This will look better then a hose clamp on the end of the EZ clip hose too. I'm glad I went this route.

Steal away! I actually got the idea from another forum, but they used AN fittings. These fittings are from Vintage Air, part numbers are:
36033-MPA - Manifold Heater Fitting (stainless) Straight 1/2” NPT to #10 male O-ring
36032-MPA - Manifold Heater Fitting (stainless) Straight 3/8” NPT to #10 male O-ring

Here's a tip: Just hit the stainless hose barb fitting a few times from different angles to work it loose and pull them from the pump. Once that's done, the hole should be large enough for the tap. Don't waste your money on the drill bits for the 1/2" tap. You'll need to drill the smaller hole a bit deeper for the 3/8" tap to go deep enough into the water pump. It gets difficult to turn the tap, so I bolted the pump back up to the block to tap it. I did tape off both the engine and water pump before I did this though.

Oh, and make sure you don't already have the 3/8" & 1/2" NPT taps before you order more. I now have two sets.

Thank you very much..I was dreading using standard heater hose.

Re: Knomadd '71 SWB C-10

I just thought of this possible issue. What do you do with the connections at the heater control valve?
