Fuel tank balance pipe hose

Great catch.
These are critical hoses and a very serious safety issue - thank you for posting this.

These hoses are often neglected and fail too soon
When I inspected 05082 shortly after purchase I saw serious micro-cracking everywhere
- Scary photo below
Replaced with Scuderia Rampante and will only use their hoses


PS - have you checked your Fuel Filler Neck hose too? That one is typically in similar condition to the cross tank fuel hoses

Peter,
Can you post pics if there are any markings on the hose?
thanks Andrew

All to common problem nowadays, cheap rubbish from the far east is flooding the markets masqueraded as SAE R9 hoses. They use a cheap rubber and it perishes quickly, months in some cases. I had Codan fuel hoses on the carbs and that perished rather quickly and when i complained to Codan they told me after examination it wasnt their hose, they kindly sent me FOC a new set and the difference was obvious.

These are the only people i found here that stock the odd size of 35mm ID bore hose and its R7 compatible, this has a higher permitivity (550g/m2/day )than R9 at 15 g/m2/day. Nobody sells 35mm R9 hoses in such short quantities and that size.

Ask them and tell them your application also check OD of the pipe with them as this stuff is rather thick.

You need NBR lined as this has the best qualities for bio fuels, abrasion and UV stability. Avoid some silicone hoses as they can be bad regarding abrasion.

Scary!
Keen eye to catch this tragedy before it happened

 

Peter,
Mine are from Maranello and are reinforced and wrapped. i checked them yesterday and seem fine. Might be best to stick with OE suppliers on these.

Thanks for the heads up on this, any word from SF?
Best Andrew

Strange because I bought hoses from Superformance and got the exact ones dgt posted photos of. They are the black hoses with the white stripe and 'triple G' logo on it. I had these on my 308 for 15 years and they looked brand new when I took them off to replace them.

Silicone is totally wrong for this application (unless it is specially made for fuel with the correct liner built in).

 

That's great Superformance stepped up and is getting you the good fuel hoses now.


Gates 253 hose marked NBR = Nitrilized Butylene Rubber
That's getting old school, most stuff now is HNBR


The Gate's White Stripe cross tank hoses were the common ones sold by Ferrari Suppliers 10+ years ago. I bought a set from Rutlands as spares, I'll look in my spares box for them to confirm the same markings as above.

 

Glad to see that SF have responded and willing to rectify the situation. What other supplier would do that after 4 + years

You are right to be concerned and agree that safety critical items need good quality but regardless of what it is, quality extends to almost everything, a badly machined tyre valve for instance can cause a major safety critical incident. So in my book quality goes with everything thats sold.

I was actually at Sf today and spoke to Colin about it and he was very concerned and will no doubt investigate the situation, but the product i purchased from them about 3 years ago looks nothing like your hoses.

As you have no doubt found out, the biggest headache for this part is the size, most manufacturers dont make 35mm bore so its a difficult item to source.

Modern fuels and the ever increasing blends of Ethanol alcohol (due to increase to E10 and even E15) are proving very troublesome with classic cars, Nitrile (NBR) is the best option as far as i can determine as its used as a liner with other products to improve strength and durability and due to its lack of ozone resistance and oxidising ageing, HNBR was developed to overcome this when used solely on its own. The 2 are quite different.

Standards mean diddly in reality as SAE and DIN have vastly differing specifications and compliance when it comes to how manufacturers blend the polymers.

As i said previously, Cohline who must be regarded as a industry standard, have been victims of fake products and no doubt others too. the item that failed on me was stamped Cohline along the carcass but was fake.

Image Unavailable, Please Login I bought these in mid 2017 From SF....guess I got lucky.

 

The parts a cheap. Would they be covering the labor costs if others had to do this work ? I doubt it and that would be the real rub.

 

Did they offer any explanation for reason(s) having previously sold lesser quality items ?

 

With the greatest respect you name one supplier that would honour replacing the items after 4+ years. Without hesitation and not knowing the full history of the item, they stepped up to the mark and did what most suppliers sadly lack. Your part looks correct item
This is not to say Peter has misused the item in any way as we all know his competence but there are lots who could of abused the part and then cried wolf when it went wrong!
Best regards
Tony

 

No offense taken, I was just making the point that the real expense in these cars is the labor. If you have to do something twice due to bad parts, that’s what would bother me. Hope you’ve been doing well Tony.

 

All good Skipp - you?

i have had parts sent out from other suppliers and they didnt fit, when i wanted to return the said item ! was told that as i had used them they couldnt be returned !!!!

Best as always

tony

 

Doing well. Too hot in the Southland for a Dino at the moment.

 

After some routine work decided to replace the fuel filter while i had the car up on the jacks and noticed this from the fuel tank to filter.
This is supposed to be SAE J30R9 fuel hose ie bio fuel proof & top spec........or is it!!!

Spoke to the supplier and he tells me the product seems to have exceeded the max bend radius and therefore the inner liner has ruptured allowing fuel to come into contact with the outer sheath, consequently dissolving the rubber. It wasnt actually leaking so how they can make that statement is beyond me but the fuel has permeated to the outer sheath somehow!

The war continues, but in this instance the supplier shut the door.

Going to try this hose to see how long that lasts

Check your hoses guys, this product only lasted 4 years
