OK, I was giving a hard time to a friend for paying over $200 each for injectors for his '97 Power Stroke. His come back was he makes up for it in that an injector pump only costs $200 instead of our $1800. Is that right, how can a $200 pump work up the needed PSI. I know his injectors are electronic, do they make the PSI and the pump just act as a lift pump?
