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.
