Re: Needing advice on vapor lock problem.
Mine has the metal line from pump run in front of block up to intake then rubber line to carb. I put pipe insulation from pump to top of intake on metal line in hopes to eliminate vapor lock. So far, 4 years and no vapor lock at all and it didn't do that before since purchase in 2015. You can get insulation at hardware store.
