flexible silicone hoses
can something like
this be suitable for all the plumbing? i've got a few awkward routs hoses need to take. can the flexible stuff be cut to
length easy/safe enough?

Should be OK, I was surprised how heavy it is....

cool  seen silicone hose world on ebay sell it as silicone ducting.
thing is, if i was to do it out of all the various bends and stuff you can buy, i'd need about 5 or 6 different bends + all the joiners, just
for the bottom hose. looking around £100 just for that. 1 length of flexible stuff should do all that (hopefully...)
does it flex easy enough? straight out the block i got an almost 180 degree bend you see

I dont like it. ok for gentle curves but it still tends to collaps a bit on the s bend I wanted.

i've tried to draw it showing the rough route, and what it goes under and over. the light blue bit is to show its behind the carbs, obviously

You are not going to be able to flex the wire wound silicone that much....
and I think it will foul the suspension
I think a better way is as follows:
Using 2 90's, 1 135 and about 400mm of ali tube

oooooooooorrrrrrrr!!!
Spencer Ashley sells this stuff off the roll with the silicone ends and its cheap as chips, apparently it is used in nuclear power stations......so
its good quality and strong (hopefully  ) and glows in the dark!!!!

the ribbed hose stuff is not ideal for good water flow due to non smooth sides.
you almost certainly will need to make up the hoses from shorter angled lengths and jiners unless you know of a car tht has the same or very similar
shaped and diameter hose which is unlikely.
with the straight hose, solde per m, tjhere is a type which as a steel spiral wire along the insdie that is supposed to stop collapsing but stil has a
limit to how tight the curves can be made.

interesting, interesting....
the first idea of the 2 90's, ali tube, and the 135 bend, i had thought that, but think i may end up with an air lock? at the top of the higher
90 degree bend?
also, what the photos don't show (as i didn't fit it for the photo) wa sthat the alternator isn't on, and means the ali tube passes
right through the middle of it, unfortunately  so a bit of a non starter
the other stuff looks interesting, not sure if it would bend the 135 degrees needed though?

the 'superflex' stuff, i think, has the wire reinforcement between the plys, and if the superflex hose is made by venair, the venair site
says inside ply is smooth
i've emailed the ebay seller if the hose bends as tight as the 135 degree bends and i'm waiting to hear back
but you're right, i've seen the rubber ones and they are terrible!

Yes it's smooth inside.
No it wont bend 130 deg in the radias shown in the pic.
what bore size do you need ?

It wouldnt work for the bottom S bend so replaced with bends and joiners.

I have an assortment of red silicone hose shapes/lengths from that chap on ebay.
one of the pieces, 25 mm ID straight just looks like the normal straight stuff - smooth outside and in - but has wire spiral - figured that out after
spending 3 hours trying to cut it with a knife LOL
strangely enough, I went and bought another metre of the same size hose but this length does not have the wire.
I suppose if I was that interested, I could try to see how tightly each can be bent before significant defoprmation occurs.

The angle isn't the problem, you need to specify the bend radius.
135 degree bends are readily available in silicone however, so a combination of alloy straight sections and silicone bends is probably the simplest
solution.

well, i don't think it would be the simplest. surely 1 pipe that does the lot is easier than 5 different pipes and their joiners, which again
adds up to over £100. £100 for 1 hose!
02GF74, could you have a test of that reinforced hose for me please? just to see how tight it can bend? that would be awesome thanks

Surely it won't take 5 hoses to do that? Depending on the diameter you may be able to bend a length of alloy pipe to fit most of the length,
with the added advantage that it will be self supporting. A long length of silicone hose will need to be supported to prevent it flapping around.
