Hey all,

My fuel pump starting to buzz pretty loudly about a month ago.  I knew that
it was atleast 10 years old, so I decided to replace it.  I replaced the
pump, filter, and all the hose in the immediate area.

About a day later, it started to buzz again.  Now, it is silent and fine for
the first 15 or 20 minutes of driving, but once the van heats up to normal
temp. (might just be coincidence?) it starts to buzz pretty loudly.

I haven't done a fuel pressure test as I don't have the gauge or hose to do
it, but what else could it be? fuel pressure regulator? I've noticed no
power loss or abnormal operation.  The van still gets about 16mpg...no
matter what I do to it!

Would love to hear suggestions from folks who have dealt with this before.

Thanks!
James
