Heat. Having a fuel line to close to hot parts used to cause vapor lock in carburetor-ed vehicles. I don't think that happens these days with EFI, I haven't seen it in a long time.

What could be the hissing sound that comes from under the car when the engine is turned off after a drive?

Could be a leak in a radiator hose, or radiator. ==Answer 2, Another Possibility== It could also be the radiator cap pressure relief valve action which vents coolant and/or coolant vapor to the coolant overflow reservoir/tank when steam is created in the coolant passages in the engine block. When the engine is shut off, the residual heat in the block can cause the additional pressure and/or steam.j3h.


What if your 1946 buick sometimes backfires and will not accelerate-what could be the cause -sometimes it seems like vapor lock?

That is the straight 8 engine, correct? Be sure the fuel filter is clean, the points are adjusted properly, the spark plugs and spark plug wires are in good condition. Vapor lock was a common problem back then. If everything else seems to check out okay and it only happens when the engine is hot, it could be a vapor lock condition. There were several remedies you could try such as wrapping the fuel line with aluminum foil where it runs close to the engine. The addition of an electric fuel pump is another option.

Are you in a warmer climate? Maybe a mountainous area. Is the engine overheated when this happens?If you answered yes to any of theses questions there maybe a vapor-lock in the fuel line.A vapor lock occurs when the fuel line runs too close to a very hot engine part, such as the exhaust manifold. The excessive heat causes the fuel to boil causing a vapor in the fuel line. this vapor blocks the line and no fuel passes.This is just one of the problems that may be occurring. More information on the engine temp and the weather when this occurs will help.
