Good morning
My mk3 2.0s has recently started cutting out (and refused to restart unless left for five or ten minutes) and the mechanic that looked at the car (and fixed what may have been overheating issues due to thermostat being in the wrong way round !) suggested it could be due to vapor lock.
His explanation was that when the heat in the engine bay reaches a high level the fuel in the lines vaporises before it gets into the engine - logically this makes sense - I'm wondering if there is a way to prevent this happening ? For example could I insulate the fuel lines ? If so what sort of material could I use ?
Thanks
Ian

Re: Vapor Lock how to stop ?
I had something similar a few years back and was looking at vapour lock but the reality seemed to be a failing fuel pump and a weak mixture so check those first perhaps.

Have a check the carb is plumbed up the right way round.
I had this problem years ago and it was simply that the feed from the fuel pump was mistakenly fed to the return outlet rather than the input side of the carb.
Tracing and swapping the hoses over cured everything instantly.
