secondary fuel system
im putting together a secondary fuel system. External A&A. But due to fuel supply from the stock pump from 4800 and up even without the sc, i am going to put an rpm switch in, in place of the hobbs switch.
im looking to have it bring the secondary pump on around 4500 rising and shut it off below 4500 on falling rpms. This should supply all the fuel i need without having to wait for the hobbs switch to work from pressure.
Anyone have experience with a good rpm switch?

I run the 50 dollar Summit one on nitrous setups. Never had a problem. That being said, I would at least hotwire the stock pump. Lingenfelter is only 200 bucks or so.
