My car will vapor lock in extreme heat gas line is insulated . why does it do this?
Vapor lock can only happen in a suction type fuel delivery system, that is when the fuel pump is located near the engine.
High temperature causes the fuel in the line to turn to vapor in a vacuum environment and the pump cannot pull the fuel past the air pocket. ( pump loses suction at the air pocket )
Modern fuel pumps are located in the fuel tank which eliminates the problem completely.
If you do have a fuel pump that is not located in the tank the line is most likely passing close to a heat source somewhere between the pump and the tank, there will be no issues from the pump to the carburetor since it is a pressure or pump type after the pump and any air will be pushed by the fuel behind it.
What else can I help you with?
Where is the suction side of a GM AC compressor?
The suction side of a GM AC compressor is located at the inlet port, where refrigerant vapor is drawn into the compressor from the evaporator. This side typically has lower pressure compared to the discharge side, which expels high-pressure refrigerant vapor. The suction line connected to this port is usually larger in diameter and may be insulated to prevent heat gain.
When driving engine gets hot and shut off?
The cause is most likely " fuel line vapor lock" This is caused when the fuel line is too close to or improperly insulated from the heat of the engine. When the engine runs and gets hot, the heat effects the fuel in the fuel line by vaporizing the fuel before it gets to the engine. The fuel is not liquid like it should be when it gets to the engine. A quick check to do is when the problem happens, lift hood and let the engine cool down for 5 to 10 minutes, then try to start it. If engine starts, it most likely points to "vapor lock". You can move the line or wrap it, insulate it to keep it from occurring.
What is fuel vapor line?
fuel vapor line is common in the car fuel line
Why would a Chevy Celebrity vapor lock?
Vapor lock is usually caused by overheating the gasoline in the fuel line so that it becomes a vapor. When the vaporized fuel reaches the fuel pump the pump stops working, the carburetor runs out of gas and the engine stalls. Look for a fuel line too close to a heat source, often the exhaust manifold or pipe then move the fuel line away from the heat source.
What is vapor locking?
A pocket of vaporized gasoline in the fuel line of an internal-combustion engine that obstructs the normal flow of fuel. Caused by excess heat on the fuel line.
What is the state of refrigerant in the liquid line?
Refrigerant in the liquid line is in a liquid state. It has condensed from its vapor form into a liquid due to the pressure and temperature conditions in the line. This liquid refrigerant is ready to enter the evaporator coil to absorb heat and undergo the phase change process again.
Why 1986 F350 Vapor lock?
A 1986 Ford F-350 may experience vapor lock if the fuel line is exposed to excessive heat. This allows the fuel to boil and prevents the carburetor from receiving a constant supply of fuel.
Why does your 76 f100 vapor lock?
HEAT insulate fuel line make /buy small-thin carb spacer, adjust float level down
Why do your clothes dry quickly in summer?
ANSWER:It works in 3 ways. It rotates or tumbles the clothes to separate the fibers from the water. It adds air to make the water vapor move to outside the dryer via the duct line. It adds heat to evaporate the water faster.
How do you fix Chevy Suburban vapor lock?
Try insulating the fuel line with a NON-FLAMMABLE material as it passes by the engine up to the fuel pump. Especially protect the fuel line from the heat of the exaust manifold.
How do you get out vapor locks on F250?
Are you certain that you are having Vapor lock ?? I haven't seen a true case of vapor lock in years...and i own a shop. Vapor lock (also called percolation) occurs when the gasoline in the fuel line boils. the fuel must get very hot for this to happen. Usually it happens on a hot summer day and the fuel line is placed too closely to an exhaust manifold. In almost every case of vapor lock i have ever seen, the car was not fuel injected but carburetted. The cure is to re-route the fuel line away from heat sources under the hood. But i must say that i would be surprised if you have an actual case of vapor lock. It is rare.
What to do about a vapor lock on truck?
wrap some aluminum foil around the fuel line close to the carburetor as possible and secure with clothes pins. This allows the excessive heat to dissipate thru the foil. It's a simple heat exchanger.
