This got me wondering, so I went to my W&B Spread sheet to check. From full to 45 min reserve, mine moves .856" aft. Header tank only, 12 gallons. Now that does not jive with Marks numbers, but that is what my spread sheet says from 12 to 3 gallons.

Heath - Lexington, SC -------Original Message------- Mine moves a little more than an inch, but if I had a only header tank it would be at least double or triple that (depending on the size of the tank).
