Rear engine hydraulic pump system option

[skymstr02]

The rear engine hydraulic is not a back up. It works in conjunction with the front system. They work hand in hand. Gear cycles faster because of increased flow.
Finding a hydraulic pump is going to be your largest challenge. They have been out of production and are very scarce to find.
Make sure that you have the IO-360 C engine because the D only has one accessory pad and you'll need two to drive the vacuum pump and the hydraulic pump.
