The hose finally came in. No, it is not plastic and does not have collars on it. I like the way it looks though. Really heavy duty and good for 250 degrees. Only place I had to shoot picture was on a nasty parts car, but you get the look.

Mark, where did you get this hose?

that is commonly available, but not like the original since it is heavier and will not flex, nor does it have the relieved flat places for the hose clamps to rest without crimping the hose,. We sell the motor mite stuff which is the correct application and flexes correctluy but still does not look right. Maybe mark whitesell will make the three needed hoses, 70-72 left short two different diameter
73-76 short
70-72 and 75.5-76 long. and the j pipe cap for the right side of 73-early 75

I got it at suremarineservice.com. 55mm hose. It is NOT cheap and you have to buy 10 ft. Figured out to be about $6.50 a foot with shipping. It's marine grade spec's.
