Vz fuel sender

[BPX-31H]

I am going to change my fuel send unit and pump as they are all in one, I was wondering will I need to take my car to Holden to get it recalibrated or anything ?

Most probably. Haha I snapped the T piece the other day, the return piece. Replaced it out now my computer says in hitting 17L/100KM
