An accelerator cable for a Suzi can be improvised with any piece on appropriately sized cable, bailing twine, wire etc... So you can remove that one from your list.
Banjo bolts for injectors and return lines. when you run out of fuel and bleed the system for the first time chances are you'll overtighten one and fracture it so it either leak or sheer the next time you touch it.
Return line is a common break but as Dougal says a couple of hose clamps and rubber hose and it's fixed.
Lets face it a 4BD1 is the sort of engine Dick Strawbridge would drive, if it ever did die it will have to be completely "insert Grimaces Sticker" or it could be bodged and beaten back to life with a ball hammer and a roll of Gaffa tape.
It's not practical to carry a LT95.
