Car Vapor Lock Problems
This category contains featured questions as examples. They relate to most vehicles.
Question: 2002 Chevrolet Astro Van, mile: 78,900. My neighbor was telling
me that his mechanic told him that car can vapor lock and stall, is this true?
Answer: Vapor lock doesn't occur in today's cars, the fuel
system is a flow return so there is no were for vapor to be, except on top of the
fuel tank.
Question: 1981 Toyota 2 WD pickup standard 22R mileage: 142,000.
What is vapor lock? How do I fix it? Do I have to pull the carburetor
off and completely rebuild it to replace the float? Is there some way to test
the fuel pump pressure without taking it to a garage and having it hooked up to
gauges? I am having some kind of fuel problem but it does not happen
all the time. These are some of the things I think could be wrong.
Thanks, Suzie
Answer: Vapor lock occurs when the fuel in the fuel system
gets to hot to stay a liquid (boils). Keeping the fuel lines away from the
heat (exhaust pipe, etc) will usually stop this from happening. Removing the
top of the carburetor is all that is necessary to replace the float. The fuel
pump can be tested on the vehicle.
