I never had a vapor lock until I put dual exhausts on my ‘46 Ford.
Every time I was in a lineup on a hot day that turkey would vapor lock.
This week I am changing the engine on a ‘46 Mercury coupe with dual exhausts.
Today I noticed the entire left exhaust pipe n muffler is within 4 inches of the fuel line, except right where the clutch pedal pivots. There it is two inches away.
The owner said on warm days it was so bad the couldn’t drive it so the put an electric fuel pump on it.
the GD fuel line is too close to the exhaust system!!
When I get done with the engine isolation I’m gonna reroute the fuel line just to prove to him what is causing the vapor lock.
