Fuel Economy Aftermarket computer info

[ARoss10661 at aol.com]

I was at a flea Market yesterday and bout a 'ZEMCO Compucruise model 44" fuel
mileage computer.  It was made in the early to mid eighties I believe.  The
thing is it is brand new.  I had to take off the original shrink wrapping.  I
got it for 5 dollars and it's original reciept says it sold for $135.  My
questions are:

1.  Does anyone sell the flow sensors etc like this computer uses?

2.  What modifications would i need to do to use it with a fuel injected
vehicle (return lines etc affecting what amount of fuel the computer thinks
the car is using)
It originally had a kit u could buy to make it work with FI.

3.  Is this company still around...does anyone know how to contact them...I
couldn't find them on the web.

Also does anyone know where I can get a GP Soreson catalog # GENGB-94?
Also does anyone have GP Sorenson's address or phone #


Thanks in advance
