I have a Mk3 escort which im in the process of putting twin dellorto 40 carbs on.
I removed the mechanical fuel pump and blanked it off, fitted the carbs, baught a fuel pressure regulator and a facet solid state fuel pump. Ive started to plumb it all in but i am confused that the dellortos dont seem to have a fuel return?
If these carbs dont use a fuel return, how does the fuel pump know when to stop pumping fuel into them??
Does the facet fuel pump simply 'cut out' when a certain amount of pressure builds up in the fuel lines??
The instructions for the pump say it needs to be connected to the oil pressure switch, is that neccesary??
All help gratefully recieved, as ive realised i dont know half as much as i thaught i did about these things!! Lol!
