        Well, at this point I have replaced the filter and the fuel line.
The fuel line seemed to help a little, but I am still not there yet,

        What seal are we talking about? Are you talking about the seal on
the shaft that is between the injection lines?  Can this be done without
removing the pump (as I do not have the tool for retiming the pump)?

        The clutch on the '79 has started to slip (bad) so I need to get
this van running (I don't want to have two of them taken apart at any one
time, the neighbors (and my wife) will get very irate) Thank you for your help.
