I have a TRANSFER FLOW 54 gallon under tank, and yesterday the ses light came on ,and my tank had 16 gallon left in the tank. I checked all the codes and they where all egr codes. I started to read the owners manual and it stated that the ses light can come on if the fuel line gets air in it ,do to running out of fuel. So i went and filled my tank back up to full and the ses light went out after a few trips. Anybody have any idea what mite be installed wrong on the tank or if anybody else had this problem. Thank you.
