Fresh Air Hose dimensions

As many times as this has been asked you would think this would be an easy question, but not so. Here is the data I have collected. Lengths are really hard to determine on installed hoses, so take lengths as approximate.

Bertybuoy Thanks for all your thoughts guys... I’m returning the 110 cm ducts and replacing them with the 80 cm variant. I simply didn’t know that there were different lengths fitted to a 750 model Spider!

giuliettaspyder That's my guess

Bertybuoy Hi Mike,
They are both the same length... I ordered 800mm, but they are definitely longer than that.
Maybe I have received the incorrect parts?

As usual your memory is correct. According to the parts manual, Veloces do have the three different sizesyou list.

But it also says Normales have two the same length.... but does not give an actual length.

You say they appear 350mm too long. What is the length of the hoses you have bought?
I am guessing that you have purchased two 1100mm ones because 1100-350 is 750mm close enough to what we think is correct.

Bertybuoy Hi Joe,
Yes, they’re both looking as if they are too long. I have one of the U clamps that will retain the duct in the wheel arch so that they don’t interfere with the wheels/tyres, and when being used there seems to be an excess in the engine bay.
I’m tempted to cut the duct, but that would really spoil the beautifully moulded ends that make a neat fit over the spigots.

jkbartusek Roy,
Are you having problems on both sides of the car?
Do you have the U shaped collar on the right side?
07-22-2019 11:36 AM
Bertybuoy So it appears that I have the right hoses then?
I have tried to compress them to make a better fit, but with little effect! There was a very small part of the original duct on one side and seemed not to have such a rigid construction- it was almost paper like, with corrugated ridges... much easier to manipulate I’m sure.
Any suggestions on how I should proceed?
Thanks again,

AlfistiSA There you go, 800mm on both sides... my memory obviously isn't that good

giuliettaspyder Both 800mm on my 101
07-22-2019 04:56 AM
jkbartusek 800 mm both sides.

AlfistiSA That sounds like the LHS Veloce hose which feeds from the LHS air collector to the air cleaner can - it's the longest hose, The others are shorter.

Alfastop give the 3 lengths as 600, 800 & 1100mm -->

If memory serves correctly...

600 is the RHS hose to the heater
800 is the LHS hose to the driver's knee
1100 is the Veloce air can feed pipe

Dave B / Bill G - any corrections ??

Bertybuoy Too long... we have tried to compress the spring, but they still either obstruct the tyres or are too long to fit under the bonnet... it looks as though they are about 350mm too long.

AlfistiSA Classic Alfa generally have their act together, is the hose too short or two long ??

As a general rule they are a PITA to get through the oval holes in the inner wings & any 'hanging up' here could result in the hose seemingly being too short
