Anyone see a problem with using a 1/4 NPT to 1/8 NPT reducer to screw the 1/4 NPT pressure switch into one of the 1/8" NPT ports on the manifold? Pic below is what I would like to do.

Does it leak?

Also, doesn't arb already bury a pressure switch somewhere in the pump assembly?
 
I ended up with a tee instead. I was thinking the solenoid ports were pipe thread but they were not and instead of trying to find a reducer I made the tee work. So what are those ports, oring boss or just compression threads? The plugs use an oring to seal.

I did something similar to this, hasn't blown up and that was 50K and many wheeling trips ago
