Hey guys, I have done fuel cells before but with a stand alone ecu. I know that the stock ecu primes the fuel pump and needs to have the float and everything working in order to start the car. What I need to know is:  
I have stock ecu with a fully built NA ka24de. I want to put my fuel cell in it and run a aftermarket pump off a toggle switch. I don’t have use for a fuel level guage or a float in the tank. I have a clear line on the bottom of the cell running to the top to let me know the level. I have a custom autometer filled cluster and I don’t see the need for the level guage when the car doesn’t see everyday driving. So does anyone have the info I need to allow the car to run normally with getting rid of the oem sending unit and installing a cell? Thank you in advance.
