I've been lurking for a long time. I have a mercedes turbo diesel, with the bosch in line injection pump, and there is DEFINATELY a small (1/8") piece of tubing that runs to the top of the IP. The NA 300d i owned previously had the altitude compensator, and it looked similar. If your IP is off of a turbo, it will absolutely have to have some sort of pressure line from the manifold to the IP that will add fuel as boost increases. If yours was missing, it'd be almost like running a NA engine.
That thing looks phenominal. Great Work. I can't wait to hear how it drives!
Videos?

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.
