I've ordered some other stuff 3mm Id, 5mm od. Off ebay, unsure of what it is as the description was poor but I'm hoping it's nylon and I can sweat it on. Only £1.68 iirc free post so I thought why not. Normal pneumatics nylon is 2,4,6mm etc id and it wouldn't seal very well when I tried it donkeys years ago on the 110. I might have a slight leak from the injector pipe or the injector washer causing my issues as the other cylinders are bone dry and no deterioration of the crinkly pipes on them. Not getting much free time at the moment to fiddle.

iirc the id is 3.2mm. It cannot be too thick otherwise it won't push on all the way because it will foul at the bottom where the gap between the nipple and the injector gets a bit tight. I've got a vague memory of one of mine being particularly short on space, probably #4.

Yeah, 3.2 , the crinkly gates stuff always has a witness mark on it off the injector nut, without measuring it I suspect its at least 5mm od, probably more.

If it's silicone, it will breath diesel fumes.
 
Not sure what it is tbh..

That's what I'm hoping, never seen it with a 3mm id though. It might sweat on snug to the nipple that normally takes 3.2.

Airline is fairly rigid made to go into couplers, it will not go over a nipple and stay there as it softens at fairly low temperatures. I have a lot of the stuff in stock, I used to make controllers for air powered systems.
 
When I had my 5 series I put an inch of heat shrink over the pipe and let the heat from the engine shrink it on. I did buy the hose from a local hydraulic place, hoping it would be of reasonable quality and it did last at least until I sold it a year or so later
 
The new stuff has just arrived. Unsure what to make of it material wise. Way too soft to be pneumatic nylon and too hard to be silicon.
I'll pop out and replace the long length between fip and number one and observe performance.
 
Impressed with the fit, properly snug. 3mm id and not as thick od as the normal stuff. Unfortunately she won't be getting used much if at all for the next maybe 10 days to test.
Doris has covid so can't go to work, the bulk of the driving, and if she's better by saturday we are off to Brighton by train on Sunday.

Well, that didn't work, 37 miles and it's leaking around the injector nipple. Shame, I had hopes for this stuff. Replaced with crinkly gates stuff again.

Just curious what size stuff it is your after? Next time I pop down the local hose place that make stuff up and what not I can always ask what they would recommend and mention how the hoses seem to keep breaking down they might have some interesting thoughts on it.

It's surprising to me that you thought you could go to Brighton AND escape leakage ?

A neighbour got some Gates stuff supposedly from the USA for a petrol car. The stuff dissolved in the tank after 18 months! There's something very strange going on. Fake stuff? Additive of some sort.

3.2mm bore. Resistant to fuel and heat. Pushes over nipples, no room for clamps and they shouldn't need them.
