l24 electronic to manual fuel pump?

[soundboi]

currently i have a l24 in my nissan laurel, c32. On these vehicles they came with a intank fuel pump, but on the return line from the engine room, there is a unit. Which acts up ever so often.

 

From my understanding that its a sensor to read fuel pressure and cuts the pump off when theres a not a need for such a amount of fuel.

 

i would like to remove the electronic fuel pump and all these electronics and swap in a mechanical fuel pump.

my question is -

 

Is there a spacer between the engine head and the fuel pump?

Do you all think it is wise to rewire the fuel pump and eliminate this stock electronic setup, just using the stock fuel pump from the system?

ill wire it up with a switch and relay setup.

 

also what fuel pressure does these carbs work best at? i have a regular two barrel carb like this
