Vanagons are notorious for engine fires, Drew. VW routed a fuel line from the tank to a steel bulkhead, and chose to use a plastic pass through fitting. Even the newest Vanagon is 27 years old now, and that plastic gets brittle with age and all that engine heat. When it breaks, fuel at full pressure quickly covers the engine, and a spark from the distributor cap sets it off. The fuel keeps coming as long as the ignition stays on, which is likely in all the ensuring excitement. Someone posts a Vanagon BBQ picture at least once a month in the Facebook Vanagon groups I hang out in, and I'm wondering why the NHTSA hasn't made VW do some kind of recall.
The early Type 1 VW Bus engines were magnesium, but I'm pretty sure they went to aluminum as time went on. Magnesium was expensive, and Germans are even more frugal than their American and Japanese counterparts. As far as I know, the Subaru engine I'm using is aluminum and steel, with steel fuel lines on the engine itself.
All the remaining fuel lines have been replaced on my van, and a thick grommet protects the new lines where they run through that bulkhead. I'm also ditching the plastic engine cover for an older steel one, and covering the foam insulation on the underside with a fire proof blanket. In addition to the BlazeCut, there will be a modern 10 lb. fire extinguisher in the main compartment, located within easy reach of the sliding door on the side. There's way too much time and money riding in that van at this point to take any chances with an engine fire.:shocked:
