Vapor lock - fuel line insulation question...

[Dshow]

Hi, I have a 2001 Mercruiser 5.7L TBI engine with a "cool fuel" adapter. After running hard and then sitting for an hour or so, it will not restart until cool again. I've seen Mercruisers service bulletin on vapor lock and am trying to minimize my heat soak and have a question:

When insulating my fuel lines, is there a "marine" vs "automotive" fuel line insulation or will any insulation due? (I wouldn't think it would matter, but I've seen the Auto vs Marine parts discussions...)

Thanks

Re: Vapor lock - fuel line insulation question...

Insulation isn't going to cure the problem. If it is vapor lock, the engine compartment is just too hot inside. Lack of air cirulation. Try leaving your blower on for a while or opening the engine cover a little to allow air circulation and see if that does the job. BEFORE you start buying stuff.
