Stop in for a cup of coffee

I may have a spare set of plug wires. I also still have the old harness, it was melted at the firewall in the under dash electrical fire the Previous Owner had.

maybe this thing just doesn’t wanna be on the road again. Maybe this is a sign.
Sure seems like bad luck, but try to do a careful postmortum. Gas spillage plus a spark or very high heat source was needed to ignite it.
At the fuel pump its an inverted flare fitting. I'd think its pretty hard to split the line at the fitting. But you'll find out when you take apart.
