i just replaced one of my long coolant pipes with wet exhaust hose. i tried to run it in a single piece from the front to the back, but the longest length i could get was 10'. i had bought 30' of 1 3/8" hose which was TOO SMALL in diameter to fit over the flange on the radiator stub and on the plastic distribution T. so i got 10' of 1 1/2" shieldsflex II (series 250) wet exhaust hose from my local west marine and it works fine. i used the original stub hose on the radiator end (the one that goes on the flange that sticks straight back out of the radiator, and is bent a couple of times before attaching to the long hose), but then cut the shieldsflex an inch too short! and had to use most of the trimmed piece to make a spacer section. to connect the spacer to the long hose, and the long hose to the front stub hose, i used dremel-trimmed pieces of the original plastic pipe and two stainless steel clams on either side of the join...used about three-inch pieces of the long coolant pipe.

bled it out and so far, so good. gonna keep an eye on it for a while, and do some freeway driving to make sure it's all ok.

shieldsflex II costs about $7/foot.

good luck! bill kasper '87 syncro westfalia santa cruz, ca
