A $2 dollar piece of hose, instead of a IP rebuild? could it be that simple of a fix to get more horsepower?

That isn't an aneroid, it's an altitude compensator. They are quite different devices but they work in the same way (reduce fuelling below the max available).
Removing the pushrod from inside the altitude compensator will disable it, allowing full fuel flow. But before you attempt any fueling mods on a diesel, you should have an EGT gauge fitted pre-turbo.
Otherwise the risk of a meltdown is a very real one.
Diesel-kiki is the japanese subsidary of Bosch, now called Zexel. It's a standard Bosch Type A pump.
