Thanks much'o for all the great help received here on the forum lately. I'd be lost without it for sure. I've got my new water pump painted and ready to mount back on this stock flat six 218,..I also purchased a new bypass elbow and elbow distribution tube from A.B. the bypass elbow looks good, (has some kind of a light tan/brown thick coating on it which looks like it might hold up a while as is)...but the water bypass elbow tube is a tad different. my old tube (which is not in the best of shape with rust/cancer) has a small hole ( which looks to perfect to have not been drilled ) in the neck of the lower smaller tube portion of the elbow tube (the tube end that screws down into the bypass elbow housing)...this new bypass elbow tube doesn't have this hole.....wondering if I need to drill out a hole like the old unit ?? Also, while I'm here - this is sorta piddly a question - but what the heck I'll go ahead and ask,....the old elbow tube was built on a 90 degree angle (or maybe someone bent it to a 90 degree angle ?? ), anyway this new tube is built on a 45 degree angle....(not sure what the plating is on the new tube but it looks descent, almost like galvanized),..course the hose connection off this tube routes to the firewall or the back of the engine block depending on if your feeding heater cores or not,...plenty of space ( I suppose ) to compensate for the hose connection at the bypass elbow with the new tube now pointing more straight upwards toward the hood, than straight backwards towards the firewall like the tube was.......if anyone can tell me which is correct, I'd appreciate knowing...and there's not much rocket science in bending a piece of pipe, but then again if this 45 degree angle was the original setup..I'd just as soon not stress the finish on part and leave it alone, aside from as mentioned above,....what might be up in regards to drilling out the hole in the tube to match my old part. Thank you all for your help. Steve
