In the U.S. the SAE spec is SAE30 R10 not T10MartinW wrote:I finally got an answer off Motorsport accessories as he eventually got an answer off the rep. It is not submersible but is fine for outside the tank. He has apologized and offered to give me a refund, however due the fact that the hose is now in Canberra I declined. I've already sent Alex a metre of SAE30 T10.

Ah, this might be the reason on Big Block, I used a piece of OEM submersible hose on the external return line, and it 'sweats' a bit, feels slightly sticky, but not quite 'wet'. I'll try an exterior graded piece to see if the issue goes away.92KK 84WW Olaf wrote:I have been replacing fuel lines and always keep a stock in my shed.
The fuel line for in tank is marked NBR/NBR meaning submersible. The fuel line for outside the tank is marked NBR/CR. You cannot interchange the uses, in tank fuel line has an issue with UV light and the outside fuel tank line is not ethanol resistant from outside.
My source was tills.de and they are a very good supplier and I suspect a volume order would be cheap.
You should be aware Honda motorcycles use the exact same size and specification fuel lines and I have been able to buy it over the counter at my local Honda dealer at a very good price as in less than AUD$2 a foot. They also use the same exhaust studs long enough for 16v/K1100 . . . . .

The Honda hose is outside the tank, not inside.Suzi Q wrote:Some of this has been covered on other threads.
But, If anyone is considering using some of the stuff sold on ebay as 'Submersible' and even marked up as SAE J30 etc. then beware that internet consensus is that all this stuff is no good. That's certainly my own experience too. It lasted about 2 years in the tank before swelling and eventually splitting. It didn't turn to goo, so I suppose you could use it if you had nothing else - a split inside the tank isn't going to kill anyone, only stop your bike.
The only guaranteed option (internet consensus again I'm afraid) is Gates, which is super-expensive in the UK. I might go looking for some of Olaf's Honda hose.
Is this the hose with accordion pleats that I see advertised with replacement fuel pumps for Bricks? If it is, the reason for its eventual collapse in Bricks could be that fuel in the tanks of Bricks generates an inordinate amount of heat in some cases. stahlbus's description of its NBR/NBR (referencing its DIN standard number) seems to indicate heat could be a problem with certain plastic.Suzi Q wrote:Some of this has been covered on other threads.

Yes, the EuroMotoElectrics fuel line is nylon. Outside of meeting SAE J30R10 they don't specify if it is Nylon6 or Nylon6/6 but in either case it is a crystalline plastic resin that has a melting point of approximately 425F or 220C.Laitch wrote:Is this the hose with accordion pleats that I see advertised with replacement fuel pumps for Bricks?

Made from the material NBR/NBR according to DIN 73379 are abrasive resistant as plastic tubing and are particularly distinguished by their temperature and heat resistance.
That's comforting; I've had bigger problems regardless—choosing between fire or flood, gales or drought, misdemeanor or felony, fight or flight, lime tarts or profiteroles. I chose NBR/NBR just to reduce dither.Point-Seven-five wrote:I seriously doubt the fuel temperature will get that high and if it does, you have bigger problems to contend with.

7.3mm would be a tight squeeze. The piece of BMW's NBR/NBR submersible fuel hose I have on my desk measures 8mm I.D. That's how it's listed in MAXBMW'S parts fiche, too.firstle wrote:all this talk about fuel line so thought i would change mine , is this the right stuff ?

That idea could hold water. Cohline's headquarters appear to be in Unit 4, Bridge Works Honley, HolmfirthDai wrote:Looks like a read-it-fast scam, because there is a Danish company called Cohlan (or similar) that does do genuine submersible pipe.

I posted this above. Maybe you should read it.TacKler wrote:I found some SAE 30 R 6 & 7 in my stash. I assume it will still do the job.
Maybe we should all read Mark 6:4. After that, cut lengths of J30R10 or NBR/NBR and flog ourselves with them prior to installing them in our fuel tanks.Point-Seven-five wrote:I posted this above. Maybe you should read it.
