My high pressure line wore through from the unused height sensor wiring at the RH corner of the tank.
If you want a temporary fix and it is there you should be able to unclip the pipe union which is about 120MM forward , cut the pipe before the leak and fit a length of 7MM high pressure fuel line with clamps. It is all very tight up there.
The other main wear place is where the pipe turns right just in front of the fuel pump. You are on your own there.
BUT you can buy either a full 4 pipe manifold from Rovakraft or similar for $270 including freight, or the high pressure line itself for about $100. ( ebay the Newcastle mob) all4x4?
Seeing you have to drop the tank to do either , I bought the full monty.
