I found some fuel pressure pumps with low PSI. This one from 2.5 to 4.5
, and from 5 to 9 PSI
but I do not know how low PSI needs to be and both of their mesh charts claim an '88 Dak is not compatible with their pump. I think it is but I still don't know which PSI is good enough to supply this carb? I don't know what I would use as a return line since this line is going strait to the carb unless the preassure is so low it just doesnt keep force on the gas in the line and won't force the float clip in the carb open.
