The 2.4 T MFI engine in the car is not expected to be permanent, so I don't want to cut a huge access panel in the firewall to adjust the MFI pump. Ultimately a 2.4 S carbed engine will take its place. In the meantime what I could use help with is the measurement that will allow me to drill a small access hole for the tool to adjust my MFI pump, which I can later plug. The car is an original six so I want to keep it as stock as possible. I know there are a number of MFI engines running in our cars. Would one of these owners by chance have the measurements for that small access hole? Or better...have the ability with seats currently out to take some measurements for me?
Without these measurements, and no access hole, it is going to be very tricky if not impossible to go in through the front of the fan with a mirror and adjust the pump. Your help is appreciated in advance. |
