What does you engine compartment fuel routing situation look like right now?

Lines flopped over too close or touching intake, block, etc can get hot faster. Bend or support line away from heat sources.

All my metal lines in the engine compartment have heat insulation on them. And they are routed as far as possible from heat sources. I run cheap California ethanol high evaporative gas with mechanical fuel pump and no pressure regulator. Never had issue and drive in 90+ degree heat at times.

May insulated fuel line does rub across that breather tube. But it's actually made out of PVC and a long path from valve cover. It doesn't retain heat. When I replace it with a metal breather crossover, I'll put some distance between the two.
