its been months and i've made 0 progress would really like to get things rolling before there is too much snow.. the stuff with red lines through it i have taken care of . but the stuff with red numbers i dont know where it goes.. if it gets plugged ect..

so any help would be awesome!

numbers 1-5 starting on the left



can 1 be plugged?

can 2 be left open ? or does it need a block off plate?


i think 3 is the fuel return line..

does 4 go to 5?
