The injection pump itself is timed to the engine, so if the pump is designed to deliver fuel at say 2° BTDC (injector needle lift is just beginning). If the lines are shortened, the fuel will begin to lift the needle 8° BTDC. Now this is messing the pump to engine timing up. If the injection line is lengthened, the amount of time for the displayed fuel to move down the injection line might cause the needle to lift 10° ATDC.
Imagine 2 garden hoses, one 50' and one 75' long, both filled with water and baking in the summer sun. Both nozzles are opened at the same time. Which one will get the cold water (out of the well) first (facet pressure being the same)? The shorter one will see cold water first.
Did I answer the question? If not, please let me know. bob
Maybe my bullet in FPS doesn't apply to this situation.
Injection systems I'm referring to are not electronic but manual.
Ok I see no correlation between the 2 garden hoses and which gets cold water "first" and the injection lines because one hose is 50% longer than the shorter hose. The injector line isn't trying to deliver "cold" fuel just "fuel". It appears to me that if the fuel is in the line and the injection pump sends fuel to that line then a working injector should spray fuel.
I suppose I can't see the forest for the trees.

This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
