The mechanical pump diesels (prior to PD engines) use a flyweight governor in the pump to reduce fuelling as the rpm increases, for the same accelerator position. The flyweights work against a staged spring system connected between the accelerator and the fuel control collar - what this means is that under light loads, the fuel supply will change depending on engine load - so if you are cruising along and you start going up hill, the engine speed decreases and the pump starts adding more fuel to compensate. Similarly, as you start to go downhill, the engine speed increases so the pump starts to cut fuel to compensate.

The only difference between the old system and the new, is that these days its entirely electronic

Ahh i see, i see ! yeah it definitely feels like an electronic thing haha
cheers mate

A bit un-nerving, but I can replicate it 100% on a couple of specific hills in the area!!
glad to know im not the only one lol
Ive just learnt not to touch the accel pedal as i coast over those hills
