I don't see why this should be an expensive repair.  It sounds like your
supply line from the pump to the motor is leaking.  You just need a length of
hose and two clamps on the ends to replace the hose that is leaking.  I would
advise you to try to get someone to come to your house and do it or get the
van towed to the garage.  I am serious, DO NOT DRIVE THE VAN IN THIS
CONDITION!!!  Engine fire is imminent and not only could you lose the van but
your life as well.  Not worth taking the chance.
