But I found a tap that required just a little larger hole than the I.D of the nipple. Drilled and tapped it for a plug, never had any issues with it. 1972 Barracuda - 5.7L Hemi, T56 Magnum 6spd - https://www.facebook.com/GoodysGotaHemi 2020 RAM 1500 [img]https://i.imgur.com/v9yezP9.jpg[/img]

No, this will be a problem , the intake is tapped to NATIONAL PIPE THREAD, NPT , so you aren't going to put a traditional BOLT in it .

Then you use a pipe plug and that gives you a very secure block off. If you stay with the water pump housing with the cast in nipple then I'd recommend a bypass hose rather than rubber cap. Just put the fitting back into the intake manifold and run a short loop of heater hose. There are lots of ways to do this, just depends on how much "hillbilly" blood you have in you!

I used this method till I upgraded to an aluminum pump and I up'd for the brass plugs. If unsure about size take the pump with you to the Napa etc.

If unsure about size take the pump with you to the Napa etc. One thing I've learned on Moparts over the years is that some people care about how stuff looks and others don't. I used to wonder about some of the advice that got handed out until I finally realized that some people are perfectly happy using a screwdriver to open the trunk. So these days I try to give a range of answers and let people pick the one that fits their budget and/or their ability.

Best is see if the nipples will come out easily w a pipe wrench or vice grips & if not heat the base threads w a small tip on the hot wrench let some candle wax (bees wax is reportedly the best) wick in then take em out & add a common hardware store pipe plug (they are NPT just like the nipples you are taking out, no drilling/retapping needed) either an internal hex or the external square (what you see in the above pic) w white teflon pipe dope or tape on the threads (w tape wrap it CW looking at the threaded end of the plug) live every 24 hour block of time like it's your last day on earth
