Did I vapor lock?


Recommended Posts

Vapor lock is happening to me pretty consistently this summer, thank you to the poster that recommended pouring lake water over the fuel pump, saved my a** today!

Is there any fuel additive that could prevent this? I use Stabil in every fill-up and it hasn't helped.

Lift the engine hatch when you sit or park after running the boat hard/long time. Getting the heat out is the best cure. Lifting the hatch lets the heat out and usually prevents heat soak(vapor lock).

Has anyone attempted to wrap insulating tape around the fuel lines and fuel pump? Any success with that?

Our boat has a seawater fuel cooler on it, and it still vapor locks. so i doubt tape would do any better. Ours is a mercruiser though, it might run hotter.
