Demister Tube

Does anyone happen to know the inside diameter of Elan S4/Sprint fresh air vent hose pipe?

1 1/4"

According to Brian Buckland's book the demister pipe is 1 1/2" dia, the fresh air vent pipe is 1" dia and the holes in the heater casing for the vent elbows are 1 1/4" dia

That's strange. I've just measured my nozzles (not installed in the car) and they are definitely 1 1/4" outside diameter. Is this what we're talking about?

Minimal parallax error.

Slight parallax error in this photo. Camera too close!

I don't know what the diameter of the elbow at the heater end is, but would hope that it's also 1 1/4" O/D, so that the hose would slip over it.

Well the ruler doesn't lie.......looks like Mr B is mistaken

elanner ... where did you get the vents ?

[pharriso]

You guys were both right... 1 1/4" ID is 1 1/2" OD (in 2013.....)

Few of the vendors specify if they are talking ID or OD....

Hard to find part, originally came from a Rover P5:

Mine came in the box of parts that accompanied the car when I purchased it. I fitted them but am pretty sure that there was a third. I can check if you're interested. It will definitely be grubby. They come up on eBay once in a while.

would love to have even one. I can then take it to my local machine shop and maybe they can make me one.
