Festus,
 The main feed is on the left side of the tank. It's the one with the tube sticking high up in the tank. I have found it easiest to start the hoses from out side of the frame by the engine, then hook them up to the tank.
 Best way to see if the hoses fit is to see if both will fit in the hole. If not, I would find a smaller hose. thumbs up                                                                                                 CT
