Bosch Pump inquires..

[Tmcilvar]

Anyway, I have two semi-ecu controlled bosch pumps, and I know there just good for a heavy paper weight.. But, one of them is slightly different to the other? One came of a D9B engine and the other of a DHX engine. The D9B engine has the different semi-ecu pump to the other, theres no cap on the back of it, and it has a max fuel screw? And I was talking to the man that I bought the engine off, and the injectors have never been changed, and theres no wire coming out of any of them? So i was wondering is it just a standard bosch pump in fancy dress or maybe its just one of the first semi-ecu pumps? For I need a pump for my 11mm head and was wondering would it be any good?
