G'day
Just after buying this truck I went to fill the sub tank and heard a rush of fluid from beneath the car. After inspection I found that the filler hose had a cable tie on it which had slowly over time worn through and split it right off (sorry for the spill caltex!). Now that it is fixed I am a bit worried about filling it up and using it as it may have god knows what in there. Mechanic suggested using an additive in the first tank or two which I forget the name of. Any suggestions?

Cheers,
Pat
