The vapor lock happened due to a exhaust leak
The fuel line doesn't have clamps. When I take this stuff off it is easier to just cut off. It doesn't pull off easily. It can but it's tough. It won't come off the plastic filter with out destroying it. No worries there
The fuel that ignited came from when attempted to free up the vapor lock. I spilled a lot of fuel. But when the fire ignited there was no open or constant source.
Yes, this was all my fault. But none of it was due to no clamps or the filter placement.
