There are NO rubber seals in the MFI fuel injection system!!! The injectors are threaded and sealed to the cylinder head with a copper sealing ring, but that is not likely to be the source of the leak! The lines from injection pump to injector are steel, and the lines are DIN double flared. A pair of flare nut wrenches are required to remove the lines from the pump and the injectors. DO NOT try removing the flare nuts without the PROPER wrenches ... irrepairable damage will probably result!!! Your leak is most likely because of rust, and the operating pressure in those lines is 260 psi, so a proper repair is probably replacement of that #5 line with an exact replacement from the dealer of your choice ... 'Excellence' has several regular advertisers that are dealers.
