To tap or not to tap the waterpump? I have the Hi-Flo kit that requires me to modify the heater hose inlet/outlet to clear the downpipe. Should I pull out the pressed fittings and tap the holes, and add some 45* or 90* fittings or just have it welded?
Be careful I've seen the water pump crack pulling out the fittings. Once they are out, I see no problem tapping the hole with NPT threads.

Look like a huge pain in the *** to tap a hole that big. Maybe Ill stop by a machine shop and talk to them about the costs. **** I might just loop the hose to itself and not worry about the heater til September. lol
I'm sure people have also overtightened the NPT fittings once tapped too. That area doesn't seem to be a real solid piece when it comes to torquing. See if you can get them out first.

Got the fittings out just fine. My issue now is that no one in this town has 1/2" or 5/8" NPT taps. I might bring it to a machine shop and have them do it. After buying taps online and shipping em it might be cheaper..
I had mine done at a machine shop. Make sure you use some sort of RTV on whatever you put in to replace these. Mine leaked the first time with just pipe tape.
Advance and Oriley auto should have those taps in stock for fairly cheap...

Got it tapped tonight. Bought some 45* elbows, hopefully that should clear the downpipe just fine. Ill have to wait til the car is running to make sure it holds water....

Do you already have the fittings to connect back to your hoses? I pulled mine out, tapped the holes and put SS allen plugs in them. I believe the holes are also 3/8 and 1/2. I'm surprised no one has made a press in bypass block since some people say their engines over heat when blocking them.
