My experience is that the fuel filter blocks - you need to carry at least one spare, and know how to change it. Once the filter is changed, you are good to go.
The fuel is pressurised to around 30psi .. that should 'clean' out most obstructions from the injectors .. you can always remove the injector/s - apply fuel pressure and power up the injectors until they 'run' .. would not do it for longer than say 30 seconds .. they can get hot. Most garages will have something for cleaning fuel systems .. you can always use that to clean the injectors - removed fuel from filter - fill filter with cleaner and run as above.. Note that diesels run injectors too .. and they do need cleaning occasional . so a truck service place can clean your injectors ...
