As well as the rubber fuel lines you might consider the internal seals of your pump and carb.
I had a 1993 4/4 and the pump failed. While replacing it I changed the rubber hoses with resistant ones and fitted a filter to protect the new pump that was E10 compliant. The pump had failed due to some bits of muck getting in from the tank. I cut it open to inspect it! I checked the tank and it was fine but flushed it out. I found bits of some material/dirt in the flushed petrol. Hence the extra filter. I replaced the main filter under the bonnet. The car had efi but I didn’t do anything forward of the filter to the injectors or pressure regulator. I cut open the original hoses to see if there was deterioration but they looked ok.
I would definitely consider upgrading the fuel system using new pipes and service kits with resistant seals. It is future proofing while you can access the parts easily.
