fi question

[Dan Simoes <dans@ans.net>]

Here's one for you Phil.

The 4kq now sports a new Bosch pump, but it's still
quite noisy.  It's been hot here over the last few days,
and a loud buzzing was quite noticable, interspersed with
the occasional "bzzt, bzzt".
I changed the fuel filter 5 minutes ago, it was not blocked
and in fact was installed in Jan, 3k miles ago.
Just in case, I swapped it with a new Bosch (made in Spain - 
my mechanic says these are trouble prone, but it's all I
can find).

The prefilter (plastic) seems OK as fuel came rushing out when
I changed the pump.  So, apart from a bad new pump, what
else could be the problem here?

I may stop at the local shop later and have them test the
FI pressure to see if that shows anything.
