Q: Le funciona stihl RB 400

Hola, Sí, esa bomba funciona para su stihl RB 400 siempre que el motor tenga un eje sólido recto de 3/4". Gracias.

Q: Can this unit be installed upside down? (180 degrees from what is shown in the images)

No,it should be install horizontally and breather up. we have more option for 3/4" shaft pump like if it works for you: https://www.amazon.com/dp/B06W9KF9JZ

Q: Where does the oil dip stick go? on axial 3wa-3925?

when pump working it sits on top of the breather tube and when you want to check the oil level should uninstall breather tube and hold it on top of the pump's body.

Q: Does this fit a Nothern Power-horse 157711a

I'm not familiar with your part number, but I bought this for my Northern Tool M45811E.3, 2.5 GPM, 3000 PSI Powerhorse pressure washer. The pump I received is identical in appearance to the original pump and works fine.
