fuel pump, fuel hose ? Options

[dax1969]

Hi guys,

Took my 74 2.0 original FI out for a spin this weekend. On my way back I stopped for groceries and when I wanted to drive home the car wouldn't start. After several attempts the car finally started but did not keep idle... I limped home (only 1 km) and immediately smelled fuel. When I got home I checked under the car and saw fuel gushing out at the front (my pump is relocated to the front near the steering rack). After turning off the engine the leak immediately stopped....
Due to the fact that fuel starts gushing out when I turn on the key I am sure that the pump still pumps fuel (IMG:style_emoticons/default/biggrin.gif)

I still have to investigate further to see if the fuel leak is coming from the pump or from a hose but ofcourse I immediately started looking on the internet/platform.

My questions :

* if the fuel pump is the culprit, which fuel pump do I need ? I know there are early and late pumps and as what I can see I have a late 2 port pump. Can I replace with the same type ? I see Bosch, Pierburg, Vemo etc.
Bosch has different type nrs 043 906091 , 0580 463016 and 0580 464085. Which one ?

* if the o-rings are the issue. Shall I try to source and replace them or is it best to install a brand new pump ?

Herebelow a pic off the current set-up (pic taken when I took out the pedal cluster for rebuild). note : I will install a different type of filter
