I was wondering if you have come up with a feedback control loop to
do this yet. I'm working on an analog method to read a fuel pressure
sensor and feedback a signal to a PWM controller.  This is to mantain
a constant fuel pressure. I already have the basics working.

If you've been working on something already, maybe two of us can
get it done faster...
