I would like to order new fuel sending unit but not sure if i have a two line 1 fuel 1 vent
i do have vent line going to my canister up front and it has cali emissions on the tank black block in center with three fuel lines 1 left 1 right 1 center
but not sure the Vent" line from the canister goes directly to the sending unit?

 

Look at the fuel pump. Does it have two ports or three? Assuming it is the correct one, that should tell you how many ports are on the sending unit.

 

it has 3 but looks new and only two hooked up, it does have a canister line & fuel line.
guess i will have to take it out first to be sure.
