I took apart the couplings for the water and fuel filter units. I

Unfortunately teflon tape has a reputation for degrading over time
when in contact with diesel fuel. Professional mechanics use a
special blue paste to seal fuel fittings.

I'm thinking a leak like this, as well. Perhaps simply reseating all the
connections -- don't overtorque -- might find the problem. I'd also look
to the bleeding valves, all three on the 2GM20F. New "wetted" gasket on
the primary filter (on the engine) might solve it.

That type of surging usually points to an air leak, one too small for
diesel.

I have removed all the fuel lines and the primary filter and replaced
the washers and gaskets and retorqued the lines. If there is a leak
I'm not sure what to test next. I am wondering if maybe the governor's
injection limiter setting is wrong. The manual makes it look easy to
adjust, but I'm guessing that they seal them at the factory for a
reason... Any thoughts on the advisability of fiddling with it or with
the likelihood that it might be the problem?
