If they had stated this was a perfect fit for Mopar 383 and 440, they would sell a ton more. It’s absolutely perfect. It fit like a charm. For all I know I will work on the 318-360 Mopar’s too. Those water pump housing ports should all be the same. They don’t have two different size ports like Chevy.Good job on this. I strongly suggest buying this for your heater bypass. So easy to install and fit perfect.

Many years ago my mechanic bypassed my heater core and recently I had to replace both heater hoses because one of them ruptured. I didn't like the way he bypassed the heater core so I ended up buying this molded heater hose and used brass connectors with stainless steel hose clamps. So far after about a month I've had no leaks and it seems to be working great. All in all I spent about $30 in parts and if I would have had it done at the dealership It would have ran me about $300 plus. The hardest thing was to get the 20 + year old heater core hoses disconnected from the engine block. That took a little bit of time and a lot of finessing. I'm very happy with the repair and I'm about 5,000 thousand miles away from hitting 100k.

This is a high quality hose that has reinforcement strings embedded in the middle. The interior diameters are 5/8" on both ends. I am using it to replace a similar hose the connects the PCV valve to the intake manifold.

I deleted the rear climate control (AC and Heat) from my Chevy Express van. This little hose made that part of the job easy, clean. Works like a charm.

Used this to bypass the heater hose in my 2003 Jeep Grand Cherokee Limited. The blend doors were stuck and it required removing the entire dashboard to fix properly, but since I live in Florida and the vehicle has heated seats, bypassing the heater was a no-brainer. Now the AC blows cold. Easy to install.
