Leaky Fuel Evap lines....HELP!

[wilko33]

so the reason the car was running wank is that it was trying to run on water....... which had got into the fuel tank through the leaky corroded evap lines running through the rear arch.

Replacing them means dropping whole rear axle, off with fuel tanka nd replacing them... new ones are £200 ($400). Any other bright ideas would be greatly appreciated, ie: somethig to wrap the lines in or cover them to protect them.... labour alone doing the other option will cripple me!

Also is there anything else I will need to replace.. fuel filter, pump, etc...
