    Gas tank deleted

    Ok what’s going on is I have a 2004 chevy Silverado 3500 cab and chassis 6.0l ls and my customer came in and wanted to remove the rear SECONDARY tank but now it won't read on the gas hand right I have looked everywhere and can't find anything on removing or recalibrating the pcm for just one tank does anyone have a idea that would help me out here because I've looked for all options and still can get anywhere I've never had anyone want to do this so I'm kind of lost on this one any help would be greatly appreciated

    Front tank is the signal for the PCM/BCM/IPC. If everything is still hooked up then it is possible you have a bad sender or cluster. Use a scan tool and do a gauge sweep test.
