Once the f/p & level sender are replaced it’s an accurate set up. I went from 1/4 tank = on empty, reserves only, to bells & whistles going off on empty means if I back into my driveway that’s on a slight incline, the truck may not start unless I roll it to street level after a new unit was installed.
A little off topic here but thought it interesting how many contractors that have e85 capable full size SUV & trucks, any manufacturer, are filling up on corn gas here in SoCal. The 1 Ton pick up with a 5th wheel towing a car carrier with 4 cars pulling into the e85 bay was a head scratcher at first. The guy said he fills up with e85 because the 6.0 loves it over the mountain pass with a load. He said the $1h fill up ain’t bad either.
The kicker yesterday was the gardener pulling all his equipment with a gorgeous black 2010’sh Esky topping off with e85. I gave him the nod of mutual respect for being so frick’n clever.
