One way would be to use a fuel pressure regulator, or any liquid pressure
regulator that is compatible with diesel.  That, or mount the fuel tank on the
roof..... ;-) Can the broken pump's guts be removed? They might be interfering
with flow also.  Cold diesel shouldn't clog it up either- if the fuel is
gelling, try mixing in some kerosene if available, or some unleaded gasoline.
 Refer to the old A1 manual for instructions on this, it's pretty
straightforward. I  have a fuel pressure reg on my Ghia for the dual weber
IDF's- it's adjustable from .5 to 5 psi.  Electric fuel pumps come in different
pressure ranges also- to make 3psi, or to make 30 psi, depends on what you
have.  If it was intended to run a car's fuel injection system, it might very
well be way too high (up in the 30's).  Facet makes one that delevers 3psi
consistently, and then you can easily regulate it to give 1.15 psi or .07 bar.
