Looks good to me. You're talking about the two smaller ones going to those two hard to reach tank nipples, I suppose. If in doubt, take the hoses out or leave them unplugged, They're for venting resp. overflow. Mine are out since I removed the tank the second or third time, hurting my fingers.
Thank you....I figured out finally that the the upper tube attached to the bottom of the tank was a vent . I'm still not sure what the lower one with the hose clamp is though . Just curious as I don't have a manual yet .
