One question, why that god d'ed awfull red tubing for connecting to the pressure/crank?
Can I just use a normal piece of silicone tubing?
Any special way to orient the pump?
What about the adjustment screw? Leave it alone or adjust it as required... problem is, which way does the screw work: Out less pumping, in, more pumping etc.
I never found silicon tubing small enough to work, so I ended up buying some small neoprene tubing at a pet store (air line for a fish tank filter).
Pump orientation is not critical, but it ought to be as close the carb as practical and on the same level, or close to it.
You may not ever need to adjust the pressure, although I've typically lowered it up to about a turn when used on an OS 160FX. You want enough to provide good pressure for any attitude, under a lot of G's, but not so much that it makes the low end needle adjustment critical. This is the consideration when used with a carb that isn't designed for use with a pump, such as that on the 160FX.
