Looking for an in-line pressure switch for Alky

[dlafont]

Does anyone know of and where I can get a pressure switch similar to the one built onto the Razor Alky motor.

I have a setup where I use a dual-stage boost controller and I want to add some safety and have the engine go to low boost if there is no pressure at the nozzle.

Thanks,

D

There are several... check out McMaster Carr... I know they have some meth/eth compatible psr switches. I used to use oil pressure switches without trouble. Depends on you mix ratio... check out a chemical compatibility chart for success.
