Thanks.I only loose the reserve at higher rpms. Example: left the marina at 5:00 am and drove at 12/1300 rpm. Trolled most of the day at 850/900 rpm. Checked the reserve at 2:00 pm and it was level. returned 20 miles at 2200/2250 rpm, 1 hour. Checked the next day when engine was cool and reserve was empty but engine tank full????
