two fuel pumps

Hi, I have just bought a 1972 Dino Coupe 2400 and am spending time looking at the changes it has gone through over the last 50 odd years. It needs a bit of work and there's a lot to do but after reading through the forum you seem to be a helpful lot, luckily for me and the car. I guess my first task is to try and get it back to some sort of originality which leads me to the fuel system. The car has the std fuel pump at the back but also has a second one fitted in the position on the front wing where the FIAMM air compressor normally sits. The second pump has its own fuel line direct from the tank dressed under the car next to the original. The std pump feeds into the rear carb as normal but the second pump feeds into the front. I've attached a sketch showing the two systems
Also the drawing shows a '4229820 union' on the forward carb rather than just a final connection, was the fuel line supposed to go elsewhere?
Thanks Paul
. I'm assuming the owner wanted more petrol in the carbs but it seems the wrong way to go about it. Any comments from anyone, was this a thing that was done back in the day? The way the entire second fuel system is taken from the tank meant that it wasn't a simple operation so they must have really wanted to do it! I thought it might be a back up system but if one failed I think the fuel would just be forced down the other 2fuel line.Also the drawing shows a '4229820 union' on the forward carb rather than just a final connection, was the fuel line supposed to go elsewhere?
