Replaced the fuel pump module inside the fuel.

Thanks. There is definetly fuel in the hose going to this device. It is rectangular in shape about 4x2 inches mounted above the drive shaft to the underside of the truck bed. The hose to it is large diameter (like a heater hose and unlike those smaller lines coming off the pump) about one inch diameter. There's fuel in the hose. Is this device designed to handle fuel vapor or liquid fuel. There were three fuel lines coming off the fuel pump. Two were of the same diameter. Looking at them head on in the direction where they coupled with the fuel lines, the two to the left were the same diameter, the one on the right was larger diameter obviously the engine feed. Of those two smaller ones I connected the one on the far left (aft) to a fuel line that ran aft to the rear of the truck. Probably going to this evap valve which is now leaking. The center fuel line ran forward to the front of the truck. Were they switched on the assembly. Thanks for responding. Paulle

. The leak stops when the gas tank cap is opened and pressure is released.I think the fuel lines to the pump are ok. The engine starts and runs good.I now see the larger recovery cannister which receives fuel lines from forward end of the truck. The large hose that goes to the leaking device originates there. The faulty condition seems to be excess pressure in the fuel tank forcing fuel out to this smaller control valve. Is there supposed to be fuel at the control valve lor just fuel vapor? Paulle
