Smartcraft SC5000 system view replacement

[newfreedom]

My Smartcraft system view SC5000 display is starting to fade. The "system view" model is specific to Searay's that have cummins 480CE. In 2006 when Searay introduced the Quantum series cummins the display went to "vessel view" After some research I understand I will lose fuel flow function if I switch to "vessel view" model.
Has anyone sucessfully switch out their smartcraft "system view"and still maintained fuel flow? If so, I am looking for recommendations.
Also, if anyone has a old SC5000 "system view" they would like to sell please contact me at smokeymack@aol.com
