Perhaps a little background first:
The fuel lines run from the right of the car (where the tank canister is) right the way to the left of the car to then go back to to the central fuel rail. This is hangover from vxl not bothering changing the basic fuel line architecture from the Astra and Vectra from which they pinched the engine.
This isn't really a problem on standard cars, other than its not very neat. It becomes more of a worry when supercharging since the aux belt is brought upwards and the fuel lines moved (or bend in most cases) fairly close to the belt.
A number of solutions exist, I made a guard which i still rather like, but in the end the best solution is to move the fuel pipes away from that area all together. Mike (Rally) designed a great system which plumbs into the original lines with a fail safe system. I've since gone right the way back to the tank in AN-6 Aeroquip fittings.
There is however a downside to it, the rail adapters which are only available from the States are both expensive and very poor in their design. Effectively on the high pressure line, you have two adapters before you get to the aeroquip fitting (as is demonstrated below), and on the return sealing is not very effective.
So here is the redesign. It may look simple but its taken a bit of effort getting there
JIC-6 at one end

Fuel rail at the other including the use of the oem seal

The American fitting (with low profile aeroquip 90 degree fitting)

And the new Mango one


I'm going to offer the first 10 at an introductory price to simply recoup my costs, this will include the return which i've not got pictures for but that much more closely resembles the US ones with a proper fiber washer.
£38 including postage for the pair. (£18 cheaper than the US one before you get stung for duties). they'll be more expensive in future so it you're thinking of doing the fuel lines sign up now.
