Jerry,

You're right.  That's why I hang out here...to try to learn from them...even
learn how to disagree.

This is the tower reflector.

Check the ARRL website, http://www.arrl.org.  Type in Fuel Pump Noise in the
search field.  You should get a number of hits.

Also, try http://www.yahoo.com and type in the same info in the search
field.

There is also a RFI reflector:
