My 3800 is in my 84 and it's hooked up but I used metal galvanized plumbing pipes to attach the water pump inlet to the lower radiator hose. I now realize that this was a bad idea. I am wondering if there is a specific hose that connects these two things oh ether on an 84 as I know the 84 is different in this aspect than all other years. Please share your input if you can help out. This is the lower rear radiator to water pump inlet hose.
