Idenifying brake lines from ABS modulator 01 Impala 3.4

Can anyone identify which wheel the brake lines (4) from the top of the ABS brake modulator on a 2001 Impala 3.4. if looking at it from the front looking to the rear?
In short just buying time with this car. Have a brake line leak which is along the firewall where all 4 are still together. Hard to trace it up to the modulator as all 4 and a few fuel lines are all bunched together and don't want to disturb as will require more immediate work.lol.
Appears to be the line to the passenger wheel.
Hoping to just disconnect and put new line in with out disturbing any of the lines.
And what size line. Parts store can't say exactly without a piece of the old?

I went to gmpartsgiant.com and put in the parameters for what I think your car is. Looking at the exploded view of the brake lines, it shows the numbers and descriptions for the four lines as follows: from left to right, facing towards the rear of the vehicle, they are, 1) 32, passenger side rear; 2) 39, passenger side front; 3) 34, driver side front; 4) 28, driver side rear. I would double check the site yourself.

Well thank you. Have added that site to favs. It will be well used. Have a good long weekend.
