Which A/C line is this on the firewall?

[FASTANG]

It had been on the header for a hour or so and melted the middle section of it.
I see there are three A/C lines available from Ford, but need to know which one I need.
They are as follows -
suction line
liquid line
discharge line

Can anyone tell me with certainty which one the yellow arrow is pointing towards.
Thanks fellas:salute:

i believe thats the one that goes from the firewall to the condenser. check ur manual. how was it able to lay on the header? :dunno:

I'm not sure on auto's but on house A/C units the suction line is always the largest line in a system. The liquid line is about HALF the size of the suction line.....there is no discharge line on home a/c units however. Looking at that pic I would say the suction is the large one on top and the lower one is the liquid :dunno:
