That is a possibility that I didn't want to contemplate. It's in
the bottom of the valley and not a fun job to get to. It does
have a bit more then the usually heard about 100,000 miles on the
pump. I guess I may have to ask about that the next time I go to
Jacksonville.

Message-ID:
Check with a diesel injection service -- I'm not familiar with
this particular pump, but a failed pressure valve or a worn rotor
will give this problem, along with low power warm. You should
NOT be able to get vapor lock, as the injection lines should be
holding pressure up to the pop pressure of the injectors! 1500
psi is typical, now way the fuel can get hot enough to boil
unless the pressure isn't holding in the lines.
Might be time for a pump overhaul, those distributor pumps often
require lubrication supplement with ultra low sulfur fuel or they
wear fast. My old Volvo pump had to be rebuilt for this reason.
