So if you have flashing fuel bars, like the guy in this video https://www.youtube.com/shorts/1hXQDHVXohQ , I can verify that B.D.F.'s fuel warning bypass WORKS.
I've had flashing fuel bars for some time due to a fried low fuel level switch. I did not have to replace the switch or mess with the whole fuel pump module. Simply plugging the dodad in place made it stop.
THANK YOU, B.D.F.!!!
