3D Texturing Gas Pump

Starting the textures for the i made all the pieces in Photoshop to make them as crisp as i could,

after that I doubled the gas pump i made before so i could have a contrast from the non-textured.
I feel like the texturing went well but could have gone a lot better, i think the main problem i have is I've got the UV mapping wrong its not quite match up properly cause i keep getting these white lines which tear across the texture, i am not quite sure how it fix this so i will have to show Robin in my next lecture.
