85 VW Golf Diesel Question (OT - Technical)

Since you all have been so helpful in the past with my Mercedes, I
thought I'd ask those in the know!  I have an 85 VW Golf running B99
from Jay's Garage for the past two years.  It isn't getting fuel to the
fuel filter anymore; the lines are dry.  All the lines are in tact, and
there is fuel in the little water separator.  It is my understanding
that the diesels haven't a fuel pump and it is the injection pump that
pulls fuel from the tank via a sending tube in the fuel gauge sender?
Maybe the biodiesel has gotten to my 21 year-old injection pump's seals?

 

If anyone knows a good diesel tech for these cars in the SE area, please
let me know.  I need to pick someone's brain as to what is wrong with my
fuel system.

 

Thanks for any help, in advance everyone.  Have a wonderful fall
morning!
