Thanks OneTrack,

 

"Found his post, it was in March, he has 17.5mm Mackay hose."

 

Now that you mention it, I do have some vague recollection. Two points;

• I will never fit a slightly overlarge hose but will, if needs be, try a slightly small eg 16.5mm ID. Reason being,  a slightly small ID will seal against the spigot, fare better than a slightly large ID.
• If aged memory serves there were questions about the age of this hose - may have been around the time that I found out "rubber" hose actually has a shelf life.

😈

Has nobody measured the spigots? They are all 18mm OD. A 16mm ID hose will be a very tight fit given the barb OD is 19mm

Confession time: No I have never measured the spigots (oil/fuel/coolant) just gone with the Rotax specification - my error.

 

It will be a few years (about 2 ) before I get the chance to measure the spigots but will try & remember to do so.

 

Just be a bit careful - some spigots , on the same system, are a diffrent OD.

 

A 16.5mm ID hose should fit a 17 mm OD spigot but as you say, asking a bit much if its actually 18/19mm.

 

My observation still stands - never go for a larger ID hose (even by a little) than the spigot OD - you will be trying to get the clamp to do the sealing for you, rather than the hose/spigot interaction..😈

Yes Skippy, I'm pretty sure I bought a couple of 90° hoses but I can't find the invoice.

 

 

I bought four of these 25mm hoses as well. If Sandra finds the invoice I'll post the list but anything not marked for the plane has just gone into a file of assorted invoices never to be seen again.

Obviously it varies between different setups, but for inspiration this is my list of hoses for my Bushcat

 

03-0010 as per moneybox

01-0007

02-0951 x 2 (datsun 120y)

 

all of these were cut to suit

All of the above are Gates coolant  25mm ID.

 

The hard to find ones are  Gates Coolant 17mm ID - if you have found any of these  - please post the part numbers.😈

It would be great if we could come up with a list of Gates 17mm ID Coolant (heater) Hose 

 

Moneybox has given us two 17mm pre shaped hoses;

• 02- 1415
• 02- 1562

The shapes  (even with cutting to length) will not suit everyone's application, so a few more,  especially ones with a longish straight section, would cover more.😈
