alright, so, doing some work on the 7. 1980 12A craper.. anyways i droped the fuel tank and did some major work to it. time come to put the gas tank back in and i realize there are four tubes....

i know what they do i just dont know which one does what.

1.output to fuel pump
2.return line
3. evap charcole canister
4. vent

consulted the haynes.... it just says to mark it before you take it off.... well seeing its a little to late to do that i was wondering if someone can give me a diagram or a drawling or something to let me know which ones which, if you live in tucson beer shal be provided for the answer.

 

The 85 FSM has the full fuel line diagram.

 

thank you. much appriciated!
