Good morning,
I would suggest replacing all 3 pumps with a suitable single high pressure pump and add a pressure gauge on the fuel ramp and a fuel pressure regulator, as I think it's the right way to run an EFI set up with minimum headaches.

I think that running 3 pumps is asking for troubles. It probably works but I find this particularly idiotic, especially when a single pump these days can do the same job on a relatively unstressed 302ci normally-aspirated engine.
Hi TTM,
You are defenitely right, however this would imply to modify completely the tank of my car; remember it is a flat underboot tank and unless inmerged into the tank, there is no other way to mount a HP pump low enough to get the necessary volume of petrol required. This is what is assured by the 2 LP pumps.
