I recently got a Sard Fuel Reg installed and was just curious when fitting an aftermarket fuel reg do you usually just change them over or leave the factory regulator their and run the fuel through it and then through the sard reg like they did with my car. Meaning two fuel regulators in series. Is this incorrectly setup or is two regs better than one.????
also use a fuel pressure gauge and take the top hose off.. it should read 40psi.. then make ur new reg 40psi without hose on and it will work a treet
