Can someone tell me if the hose on the front/center of the engine should be there. I am thinking my 1994 does not have the hose, but is instead capped (I don't have the 94 to look at here). The hose attaches to the front of the block and goes to a small check valve of some sort, then to the bottom of the gas tank. The hose is cracked and needs to be replaced if I don't need to cap it. See photo.
