I dont post here often but this is important. 4 years ago I sent my 348 in to a local independent service centre (highly recommended by the dealer who sold me the car many years ago) for a cam belt. I'm getting too old to tackle things like that anymore. When done, one of the items on the invoice was 'make up & fit new fuel lines - 2 metres @ £7.84 /m' I thought no more about it until a couple of days ago when I started the car up after a couple of months of disuse and there was an immediate smell of fuel. The impressive looking stainless steel braided pipe was spraying fuel over the exhaust manifold and cat. Fortunately as the exhaust was cold there was no fire. Had it been hot, this would have been the end of the car. I pressure tested the hose which had catastrophically failed. on dissection and examination the thin rubber liner was degraded, split and cracked. Cheap hose is not worth the risk. As a pilot, I'm familiar with Aeroquip hoses which are used for fuel and oil lines on aircraft and last for many years without degredation. Routine practice is to replace them at 10 years. Aeroquip 601 #6 hose with aviation certification is about £50 per metre and would be gold standard. It is also available from automotive suppliers without certification for £25 per metre - but be careful of fake Chinese hose. If genuine, this hose would be fine too. Hose at £7 a metre is not fit or safe to use on a Ferrari. Phil. Picture of offending hose and the liner stripped out of a section of pipe.
