Cory, I am on a VW forum. It is no secret that early Bugs and Buses/Vanagons are susceptible to engine fires for a number of reason (faulty fuel filters, fuel lines, oil leaks). Many owners of earlier VW bugs and Buses/Vanagons have installed Blazecut extinguishers on their vehicles as a precaution for this reason.
Early extinguishing or suppressing of a fire (particularly in early VWs) is a key element in minimizing vehicle damage.
I'm guessing that those more expert than I will chime in with more knowledgeable and expert information than I can provide. @Jim Kelly
