L322 4.2 SC Fuel Rail Crossover hose replacement
 

To all, Does anyone have any idea of how or what hose(size) to use to replace the fuel rail crossover hose on a 2006 LR RR 4.2 Jaguar Supercharged engine. While replace the infamous coolant hoses which were leaking under the supercharger I notice the fuel rail rubber crossover hose was cracked and leaking as well.. At first I thought well its just another hose to replace simple enough, until I was informed by my RR dealer that you had buy/purchase the entire fuel rail manifold as no one provides just the hose replacement. My response was, Its only a push on style (high pressure) hose which uses ****** fittings for connection. Once again the dealer informed me that for only $1800.00 PLUS TAX of course i would have to purchase the whole fuel rail assembly! If anyone can provide me any alternative options for this hose replacement I would be very grateful..
