When I gas it up it vapor locks and spits gas out the vent holes I have it just barely in the spout and have to go real slow

Are you talking about filling the gas tank>> If yes,,, That is NOT vapor lock... thats just the angle, speed of delivery, size of hose in vehicle, etc that causes the gas to spit out,, try not putting it in so far, and use a different angle.. (mine does the same thing!)..

Vapor Lock is when the engine/carb get so hot that the fuel vaporizes in the fuel lines and carb...THEN "vapor" cannot be pumped into the engine... and it wont run... now ya know!! :)

93 ford tempo vapor lock

What part of the country are you located in? is it hot in that area alot? see if you can follow your fuel lines if they are not inside of a frame rail from the fuel tank forward. you could wrap your fuel line once it comes out of the rail going to the fuel distribution area of the motor. it might be to close to a heat source which boils the fuel before it get to atomized.

I have a1977 motor home with a 460 ford engine it runs good for 4-5 miles then looses power i can stop then take off again runs good a little ways then does it again getting worse the farther you drive it....

The problem is deffenatly fuel related. Possably a weak fuel pump if you have replaced the filters meaning all filters even in the pump . But the when hot could also be what is called vapor lock in the fuel line so air is getting in the fuel line for what ever reason and when the vehicle gets to opperating tempature its building up pressure inside the fuel line stoping the fuel flow to the carburator . If this is it you can fix it buy adding a accressery filter before the steel line begins . Or it could be the power valve in the carburator or the inlet filter in the carb or the carburator just need to be rebuild if its a 2 berral its not a problem if its a 4 it may be more of a problem . See what you can do with it

The engine sputters and dies when it heats up. Is this Vapor lock? On cold start it works great and idles just fine but as it heats, the engine starts choking and soon dies out. If this is vapor lock, how...

sounds like the reason it starts and idles fine at start up is your choke is functioning... as your vehicle warms up.. the choke starts to kick off... Inspect your throttle body and idle control motor.

Truck after engine gets hot starts sputtering

You're getting a condition known as "vapor lock" or hydrostatic lock. This happens when you run your fule lines too close to a heat source (exhaust, engine, etc). You can solve it by re-routing it away from those heat sopurces...this should help.
