The chances of this happening now to the pumpers is somewhat remote now!
Well, to SAMFS Scania's anyhow.
There was a extensive modification performed on all the Scania's in the fleet, which included not just a mesh filter, but a whole new alloy air filter box to replace the plastic one, new fire resistant hoses and fittings, and a fire resistant air filter.
I know this, because I did ours!
