What can I do to reduce vapor locking in my engine?
Increasing engine compartment ventilation to move the hot air out of it during a ‘heat soak’ will decrease vapor locking. Other items that can help reduce vapor locking are: Letting an engine idle for 3-5 minutes before shutting it off. Open the engine cover to let the hot air escape.
What to do if your fuel delivery system is vapor locked?
Crank the engine using the remote switch. As the engine cranks, spray a shot of starting fluid through the throttle valve. If the engine seems to catch while spraying the starting fluid, there’s a good chance the fuel delivery system is vapor locked. You can do a similar test using a small plastic bag with ice:
What to do when your outboard engine cuts out?

How can I prevent my fuel lines from overheating?
There are several potential solutions to prevent fuel lines from overheating and solve vapor lock issues in a carbureted or, when necessary, in a fuel injected engine. For example: Check that fuel pump and fuel lines, including the one between the pump and carburetor, are not too close or touching hot engine components.
What to do when your car has vapor lock?
After your warmed engine stalls, pull to the side of the road. Open the hood. Place a bag of ice on the fuel line between the fuel pump and carburetor and the one that connects to the fuel pump to bring down the fuel line’s temperature and allow vapor fuel to condense. After a few minutes, try starting the engine.
What to do when your fuel line is bleeding air?
Open the bleed plug on the filter closest to the fuel tank. 6. Open fuel supply valve so that the fuel is available to the filter and pump. 7. Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full
What causes air to be trapped in a diesel filter?
When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel.
