Ok; it's but a baby mileage wise, but a clue may be so few miles
since it was built. Bad things happen, especially to fuel systems
when vehicles sit... My guess is the fuel filter/pressures regulator
is sticky. Some dingleberry decided that the regulator should be
clamped onto the end of the filter (?), as seen in this photo:

item the silly price of about $110 dollars, and no substitutes.
Before assuming I'm correct, dig thru here, and maybe pose the
question to the collective on this forum (The Chain Gang):
