and if it acts as a water separator, even better!

Racor - which one?

Hothead - looks like it uses Racor filter elements (http://www.vegpower.com/order/prodpage.cfm?cat_selected=92&product_selected=240&startrow=1)

Davco - model 234 looks pretty good (http://www.frybrid.com/parts1.htm#heat)

I've been happy with the Racor 1000FH, I go roughly 5000 miles on a filter.
