Why is fuel leaking out of the overflow hose that comes from the top of the fuel pump once I turn the truck off?

Does the pump have wick disconnects that required a tool to remove them? There are orings in those as well as a large oring sealing the pump to the tank. Make sure the connectors click when you replace them. The pump should activate with the key on. " not started", you should be able to see if the lines are leaking or if it just your fuel fill overflow hose leading to the fill door alongside the large full hose.

google youtube and find out if there is a video pertaining to changing your fuel pump..U might be able to access it from under the back seat or from in the trunk...there for u wont have to drop the tank..sounds like a bad fuel hose from tank to fuel filter via Engine

code p0441 refers to evaporative emission (EVAP) system--incorrect flow detected====causes -hose connections ---intake leak---EVAP canister purge valve. Check for vacuum leaks including vacuum controls for the vents or replace the purge valve.

There are two hoses running from the filler neck. Either of them could be leaking from the top. There is also a seal on the top of the tank where the fuel pump is that can leak. If your car leaks the whole time you are putting fuel in, I would suspect the hoses. If it only leaks when you get it full, then check the seal on the top of the tank. The top of the tank can be seen without dropping the tank. Remove your back seat and you will see a cover over the fuel pump. Remove that cover and you can see the top of the tank.

CAR OVERHEATING FIRST CHECK FOR LOW COOLANT IN THE RADIATOR COOLANT OVERFLOW JUG.IF COOLANT LEVEL IN OVERFLOW JUG LOW REFILL ADD COOLANT BACK TO THE FULL COLD MARK.PUT RADAITOR CAP ON COOLANT OVERFLOW JUG START ENGINE LET IT IDLE UNTIL IT OPERATING TEMPERATURE.MAKE SURE TOP RADIATOR HOSE GETTING HOT WHILE ENGINE WARM UP.IF TOP RADIATOR HOSE DONT GET HOT WHILE ENGINE IDLING YOUR THERMOSTAT COULD BE STUCK CLOSE CAUSING CAR TO OVERHEAT.IF TOP HOSE IS GETTING HOT.CHECK FOR COOLANT LEAKS CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE FOR LEAKS.CHECK FOR LEAKS AT THE RADIATOR CORES AND PLASTIC SIDE CONTAINERS.IF ALL IS GOOD ENGINE OVERHEATING WHILE IN A LONG TRAFFIC LINE, COOLANT FANS NOT COMING ON.COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR BLOWN COOLING FAN FUSE OR RELAY.COULD HAVE PCM FAULT.MAKE COOLING FAN ELECTRICAL CONNECTORS AND WIRING NOT DAMAGE OR BROKEN.

In a properly working system, the coolant expands as the coolant temp rises. The excess coolant flows into the overflow container by the hose that runs from the bottom of the overflow to the top of the radiator, under the radiator cap. When the coolant begins to cool down, it contracts,drawing fluid back into the radiator from the overflow. The water pump has a "weep" hole located near the bottom of the pump housing that will leak coolant if the pump is going bad. In some engines, the 3.0, the water pump is located under the camshaft timing belt cover, and is a BEAR to deal with. However, the coolant should be pulled into the radiator when the engine cools, so check that the hose from the top of the radiator is attached to the bottom of the overflow and that it is not blocked or pinched. Have the system pressure tested to verify that it has no leaks. Hope this helps. Dano

theres usually an overflow hose or breather hose that comes off the top of the gas tank or fuel pump..... and the hose is probably clogged you can take it in and they will fix for you for a hundred bucks maybe or you can just look at your hoses and see which one is clogged . do a little investigating :) any questions let me know :)

Are you talking about the 2 inch water hose at the top ,or the overflow line about 1 half inch coming out of the radiator cap. If it is leaking from the radiator, replace the radiator, if it is coming out of the overflow, replace the radiator cap. If it is coming out of the top radiator hose then replace the hose

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank(not the cap),this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.

you need to get your car to a car shop so they can put it on a lift to see what is wrong. fuel leak can be very dangerous.
there is a fuel pump gasket on the top of the tank
there is a filler hose goes to the side of the tank
there are a pressure hose and a return hose go to the top of the tank
there are evaporation hoses on top of the tank as well.
rubber hoses are getting old and crack easily
so there are many possibiltities that can cause leak
