I understand that the Vanagon with fuel injection are likely to burn down to the ground - possibly bad hoses. I noticed a major company has a kit of fuel lines that have a 30R9 rating. Their cost is 63.99+/- I am in Missouri, we have a lot of ethanol in the gasoline- for most of the year. I understand we are looking at 12-14%, Dow. The fuel lines that were on my 84 Vanagon - "Conti din 73379 E7x3k 50.83" The fuel lines are hard as a brick. Who makes a fuel line that has the 30R9 rating that will hold up to ethanol?
Are the Conti fuel lines made in us or Europe - It is obvious that these will fail

Most any major hose manufacturer will have 30r9 fuel line. Gates also has their Barricade Fuel Injection Hose which is a high pressure variant of their 30r14 fuel line. Note that you want the high pressure stuff not the normal low pressure 30r14 line.

many autoparts store sell lined hose. just look for the SAE 30R 9 label printed on the hose. It is very common to find that hose in English (inch ) sizes rather than metric. No problem as 5/16th inch works just fine.

so look for any brand of 30R9 5/16th inch hose. if it is 30R9 it will be the right pressure rating and will be lined for protection from todays government mandated fuels

There is a thread around here with a link to Amazon that has very good pricing on the proper hose.
I bought a bunch of spools and they were all delivered.

I'm gonna have to disagree here. My experience with 5/16 J30R9 hose informs me that it is not "just fine" when mated to our 7mm fuel lines and fittings.

5/16" translates to 7.9 mm. I found that to get a reliable leak-free connection, I needed to double-clamp or even triple clamp the 5/16 hose, depending on the location (triple-clamp was needed on the pressurized black plastic hard-line just forward of the firewall).

Fortunately, a metric solution exists: Cohline 2240-series hose is a low-permeation hose suitable for bio-diesel applications. It's like the European equivalent of J30R9.

In case you've never heard of them, Cohline is the OEM supplier of fuel hoses to Porsche, BMW and Mercedes Benz.

The hose to get for most of the Vanagon fuel lines is Cohline 2240.0600. It's got an I.D. of 7.3 mm, which is a perfect snug fit on our fuel fittings. Google for it and you'll get a number of hits. Both GoWesty and Pelican Parts carry it. If you want to finish off your installation cleanly, use Oetiker 16700013 ear clamps on this size of hose.

Additionally, Cohline 2240.1019 has an I.D. of 11.5 mm, which would make it perfect for the short stub of hose feeding the Vanagon fuel pump. I've just ordered a meter of this hose from Pelican. After I've installed the amount that I'll need for my Vanagon, I'll consider selling off the remainder at a buck-an-inch, plus shipping, if anyone is interested.

Single hose clamp works fine for the 5/16 th inch hose, never a problem on several engines I have put together. been using 5/16 th inch hose for decades on these motors with zero problems. maybe the hose clamp your using is too big to fully tighten??

The fittings are actually ~8mm and not 7mm, this makes the ID of the fitting about the same as that of the hose. I have been using 5/16 for decades with zero problems, typically 5/16" hose is 7.9mm or smaller inside.

VW almost always uses a hose that has a very close ID to the fitting which can make getting a replacement hose (with the same ID as the original) onto a fitting difficult at times. A 1.5 mm ID hose may need to fit over a 2.5 OD fitting and thus go on grudgingly.

Bully for you both.
I'm not going to get drawn into a typical Samba pissing match here, just letting the OP know that there is a metric alternative which is, in my personal experience, superior to the inch-only J30R9.
He, and you, are free to do what you will with the information.

As stated j30r9 rating is inherently only in an imperial sizing system and (as far as I know) not available in any metric sizes. Additionally, we are the only nation that runs such absurdly corrosive fuels as the standard these days.

So, if you've found a hose in a metric size rated for international fuels and markets, that's fine, but our fuel is just shy of pure evil. It's probably not meant for long exposure to our fuel.
J30r9 is.

I'll be sticking to the 5/16" Goodyear hose for a long time, it's the only thing I've seen hold up on many many vanagons.

A bit different, but similar.

https://www.brickwerks.co.uk/index.php/brickwerks-blog/fuel-hose-information-and-reassurances/

73379-3 is the most recent DIN standard as far as I'm aware.

I don't see on your site that the unnamed hose hose you sell meets the 73379-3 standard or even what the 73379-3 standard is. Nor do I see anything that definitively says that it has a better permeability rating than any other 30r9 hose. :cry:

Sat Oct 17, 2015 12:10 pm

Data here.
https://www.brickwerks.co.uk/index.php/fuel-hose-7-3mm-bio-rme.html

It's the same stuff that's factory fit on the last T5, not sure what they are using on the T6, not had the opportunity to check.

Sat Oct 17, 2015 1:15 pm

I looked at that page previously, but unless I missed it it says nothing about the DIN 73379-3 standard or the permeability and brand of the hose. Except that it vaguely implies otherwise I see nothing to make me think it is anything but standard 30r9 hose.

I will admit that I have no idea what the VW TL 524 24, GME 08 007, DBL 6256.70, and BMW GS 93010 standards are.

Of course none of that helps us here in North America since you won't ship your products here. Unless that has changed? (please say it has!)

However, GoWesty does sell this stuff, bloody expensive but seems to be the goods.

I bought some for my Zetec, Syncro fuel tank reinstall, fortunately didn't need a lot. Real nice fit compared to the US standard.

It wasn't an advert, just some more info for you that all.

Sat Oct 17, 2015 1:22 pm

I also simply stated that as far as I am aware the latest DIN standard is 73379-3, that was all.
I love the samba, such a chilled out bunch.....
I would buy your hose from Pelican, it's good stuff. ;-)

Yep, all good. Just a heads up to those who don't already know so they don't waste their time/frustration trying to order from you.

Re: sizes.

4mm tail - 3.2mm hose.
6mm tail - 5.5mm hose.
8mm tail - 7.3mm hose.

we've had trouble with hose marked NBR/CR, nitrile inner, abrasion resistant outer.
The stuff Pelican sell is FPM/AR/ECO.
FPM is also called FKM.
FKM is Viton, fluorocarbon rubber, used as the liner.
AR is Aramid,used as reinforcement.
ECO isEpichlorohydrin Copolymer Rubber (I Googled that one) but that's the outer.
