I am not sure about this at all.
Probably meant to write that
 it is sucking diesel through someplace into the pump.

I had not intended to put this problem to the group yet.
 I had just observed the air but not investigated furthur.
The innline is clear, just where the returnline goes out  you can
visibly see air gushing out about every 4 or so  cycles.
My first guess is to chance another out line and observe.
 There are no fuel leaks at the injector pipes or the fuel return hoses.
