Is there any way to calibrate the fuel senders?
Just returned from a 5000 mile trip (full report later).
What I found was that when my gauges read dead empty (both main and aux) the tanks are still half full.
At dead empty on both gauges the coach takes 25ish gallons to full again (confirmed full, not from gauge)
I know the general rule of drive 300 miles and fill, but that does not help my brain be okay with driving under empty in the middle of the desert when it's 100+ outside. This also makes it tough to know when to switch to AUX.
I know how the tanks work and the crossovers etc, I'm just asking about the senders themselves, is there a way to calibrate them to read empty?
