vent hooks to vacuum hose, sucks the vapor into the engine so that it doesn't escape into the atmosphere and cause smog.

If your about to drop the tank to work on, or change the fuel pump, it's said by those that have done it, that it's easier to disconnect the fuel filler hose, tail light wiring harness connector, remove the tailgate to make te bed lighter, then unbolt & slide the bed back to rest the front on the rear tires, the back portion on saw horses.

Then you can access the fuel pump without having to disconnect the fuel fller hose, drain & drop the tank, which is said to be a bigger pia.

Yup as has been said, there is a vacuum line at the tank that goes to the vapor recovery canister & those tank fumes are recovered & used to help the engine start & run easier when cold, so that hose needs to be hooked up & in good condition for the engine to run right, have lower emissions & prevent vapor recovery system trouble codes.

Question about this vapor recovery system: similar no start problem (year 2000 explorer with 4.0 L OHV engine). Replaced fuel pump assembly, fuel filter; have low pressure at fuel rail but engine will run for a few seconds with gas squirted into intake manifold. Voltage at connecter to fuel pump reads 10+ volts. I don't get any DTC codes because battery was disconnected to replace fuel tank. I figured that camshaft posetion and crank postion sensor are OK since engine will run for few seconds.
thanks for any help.
