Hi,
My 94 Altima had a small fuel leak at the rubber hose just before the fuel filter. I replaced the rubber hoses from the metal tube (from fuel pump) to the fuel filter and from the fuel filter to the injection tube. In this process, I had to move the vapor canister to get to the hose claim on the metal tube from fuel pump side. Now, it is hard to start (it will start after couple cranks) if the car is off for a while. It starts fine after the engine just turned off. It was starting fine every time before the hoses replacement. The fuel hoses do have fuel pressure when the key is turned on. It seems to me that the fuel in the fuel line got drained back to the tank after the engine is turned off for a while, is this normal? Should the fuel drain back to the fuel tank? I checked the hoses around the canister and can not fine any thing wrong with them. Is there a one way flow device in the hose just before fuel filter hose? I replaced the fuel filter also, but it still has the same problem. What is wrong? Help please and thanks!
