fuel hose perishing
im trying to find fuel hose that doesn't perish due to modern fuel having alcohol based additives, ive the cheap BS AU 108 hose, apparently
Gates sell SAE 30 R9 in the USA that is lined with Fluoroelastomer/Nitrile which withstands this new modern fuel but surely if were using the same
fuel over here we ought to be able to get the same sought of hose in the UK, where can i find this stuff as im fed up having to replace my hoses every
couple of years, surely i'm not the only person in the UK that has this problem, is this the stuff??

Yep. That's where I got mine from and it is marked R9 when it comes. (Apparently, some other ebay sellers have sent R6 instead of R9 to members
in the past)

Have a read of the post at the top of the engine & transmission section of the forum by David Jenkins titled Fuel pipe research, some useful
information there!

It should be illegal to sell the R6 nowadays.... Stuff thats been on a year in my car is hard and brittle.
wasn't aware of nitrile lined r9 stuff till i read the sticky at the top of page.

It's a problem that will affect kit cars and classic cars more than most, as it's stale fuel that does the worst damage - so if you lay up
your car over the winter then I recommend that you take a close look at your rubber pipes in the spring. Or drain the system!

I have had to replace a few sections on my car over the last couple of years mainly at the back near the tank the length under the bonnet that has
always been there is still perfect but don't know where it came from.
A few years ago when unleaded was first introduced I had a leak on the pipe from the fuel tank on my tin top , when I went to the motor factors for a
replacement section they knew then that unleaded caused a problem and sold me some green coloured fuel pipe that was specially for unleaded but
haven't seen any since.

My previous posting on this subject, (post started by David Jenkins on 4/4/11):-
Since this problem was first posted I have kept a regular check on my hoses. I have checked them again today and they all look fine, no cracks, no
leaks and no smell. They have been in use since around 2004/5, so 6 or 7 years, so I thought it worth posting some details of the hose here.
It came with the new carburettor I bought from Southern Carburettors in April 2004 and he markings on the hose are:
Webcon UK BE 4012 WP Leaded/Unleaded 7,4 3Q01

I got some marine grade fuel hose, marked ISO 7840 (i think?)
hopefully will stand up better than normal car stuff. its fire resistant too.
any thoughts on this type of stuff?
not sure on pressure ratings and stuff though. i'm on carbs, not sure if its any good for injection.
edit, iso7840 rated up to 0.34 MPa which is 49psi? what does an injection system run at?

ok guys the buzzwords are fluoroelastomer lined hose, ive written to webcon for clarification of their hose & the 7480 stuff on the goodyear site
makes no ref to this lining
LINK
the right stuff
the right stuff2
heres a useful video i found about hoses although barricade is a bit OTT as it can be used up to 100% ethanol

I wish I could get hold of the stuff that's fitted to my ex-bike fuel pump... it''s a short length of grey, very flexible and soft
hose that has NEVER shown any sign of rotting. I've never seen anything like it elsewhere, and it's no good going to a bike shop to get
some more, as it's a specially moulded piece designed for a specific bike pump.
Thinking of bike shops - I did get offered some thin-wall fuel pipe in the local Honda dealership that was supposed to be up to modern standards, but
it didn't have any markings so I didn't want to risk it (it's a total PITA changing the flexible hoses in my car). Might be worth
investigating that route, as they often sell stuff that's totally different to what you find in car outlets.
Andy - you wouldn't believe how hard it is to find that proper fuel pipe. I even tried emailing Gates in the UK, and they didn't even
know what I was talking about - and I quoted the Gates' US part numbers!
The marine stuff is very good, but still not as good as R9. Its main claim to fame is that it can resist fire for quite a long time (e.g. an
engine-room fire on a boat) rather than resistance to fuel.
What I REALLY wanted was some Gates hose I found on their US site - fluoro lined for ethanol, but thin-walled for use with carbs. No way I can find
that in Europe...

I used some hydraulic hose on my car for the link from the swirl pot to the inlet of the fuel pump, it is 15mm bore and has never perished so maybe
hydraulic hose may be worth looking at.

No way they would ship you some then? What about you order a decent amount and then flog it on here? Make you some pocket money for all the efforts
you've put into this research? I'd certainly buy a metre or 2 from you.
Silly question, but is there any connection with the lower RON value that I believe US fuel has? It's about 91 to our 95 isn't it? With
the Japanese even higher? Just wondering if that has any effect on this subject?
Cheers,
James

yeh, SAE30 R9 or DIN 73379-3D lined with FKM fluoroelastomer is impossible to find in the UK as most venders who say they sell it cant verify it has
SAE 30 R9 or 73379-3D stamped on the side.
Goodyear, Gates & Dupont sell it in the USA so its strange how they dont want to conquer europe??
Cohline in Germany who supply BMW say they sell it but again with no suitable description on the hose im dubious.
Car Builder Solutions say they might have some by the end of the month so fingers crossed, all you guys thinking SAE30 R7 or DIN 73379-2 nitrile hose
is OK think again, look at the link below

As stated previously, The ebay link you had in your original post is where I got my fuel hose from - and it was stamped SAE R9 along its length. I
also noticed it had a blue coloured lining which presumably is the fluoroelastomer you are referring to?

Advanced Fluid Solutions sell Cohline hose so i spoke to Cohline who told me their product type 2240 was the one i needed, i found 2240 is 77339-3E
or bio-diesel hose as seen on the 3rd page of this link, so can i only assume 3D is SAE 30R9 bio-petrol & 3E is SAE 30 R9 bio-diesel? 3D uses FKM
as a liner as per gates, goodyear & dupont, 3E uses FPM/ ECO.
link
as 3D seems unobtainable in europe & at only £4.45/m i think im going to say sod this & just go for it like you andrew

Andy,
Didn't realise there are two types of SAE J30 R9 so I nipped into the garage to take photo of the hose I bought from Advanced Fluid
Solutions.
As can be seen, there's no manufacturer's mark and no other mark to to i.d which specific R9 hose it is.
Still, it's R9 so hopefully it'll be better than the perished hoses previously fitted on my Cobra

great, would you be able to take a photo end on of this blue protective lining that you mentioned as this seems to be the crucial lining that protects
the outer rubber from the ethanol?

I have bought this for my fuel hoses:
8mm 5/16' Silicone Fuel & Oil Hose Flouro 1 Metre Blue | eBay
quote:
Fluoro Lined Silicone Hoses ensure hoses can be in contact with Fuel & Oil unlike standard Silicone Hoses. Designed for direct transfer of
petrol and oil. Made with a fluorsilicone liner and 3 polyester outer for strength and flexibility. Not for continuous immersion in fuel or
oil.
It has an inner fluoro lining but that last little bit is slightly concerning about not being suitable for continuous immersion. I dont if thats just
because the outer wall is not fuel or resistant so it cant go inside a fuel tank for instance, or if the pipes should not have fuel inside them
continuously.

Its just that they shouldnt be used where fuel would be in constant contact with the outer layer.

Not all fluoro linings are blue. The stuff I've got is lined, but the lining is black - in a black outer - useful...
R10 is the one for continuous immersion, but there's no harm in using it in the normal way.
