How to Rewire Your Fuel Pump FC3S RX7 | Ep 24

Описание: In this episode, I show you 3 different ways to rewire the fuel pump on the RX7. Why rewire the fuel pump? The FC3S has a resistor relay box which varies the voltage to the fuel pump in an attempt to prolong the life of the pump. However, this variance in voltage, combined with 30 year old technology, is not the most reliable means to deliver power to the pump. So, we throw it in the trash! We are more concerned about consistent voltage/pressure than durability of the pump. Protect the engine at all cost!

Old video explaining my Fuel Pump voltage drop:

(It's not my best work, but the proof is there, ~0.5 V drop across the old system)
