Ha Ha Ha...But I do hope it works.
Yes you need a fuel pump. FI usually uses 100 psi or close to it. And a return line too, so the gas tank gets really hot.
The system using a Mass Air Flow (MAF) is usually considered the best but it can be done with out that. I forget what it's called but relies on more computer data and less real time data.
A manifold Air Pressure Sensor and a Barometric Air Pressure Sensor. Sometimes one sensor can do both of these.
What you really need is a kit isn't it? Or can you write the program for this yourself.
Please tell us more.
