All good stuff but if you can put a 4 to 6" loop in the hose going to the vertically mounted puke tank. On a CR II car it is very easy-and room for it- on the back wall of the trunk, outside of the trunk.
Fuel: with another neck? Where is the 90' overflow valve? Should, if it doesn't go by the seal on the cap should run into the overflow/vent and return to the tank.
Location of the diff vent- about an inch tall usually found on the top of the right (?) axle housing past the pumpkin. What is being forced out is the
oil that is to supply the axle bearings.
You guys are driving hard.....coool!
