fpss setup
fpss setup Does anyone have any advice on how to set it up?? I know how to with a meter and lots of nitrous . But is there a way to just set it low for you know it wont hit below that mark enless the pump goes out? what pressure does the switch drop out at? This is for a 125-150 shot . I am just looking for a way to just set it without having to use half a bottle of liquid gold .
I just hooked mine up to my air compressor and used my volt meter as a continuity tester. I watched my guage on my aircompressor regulator and started at 0 psi. I slowly turned the pressure up until the fpss made contact at about 38 psi. I could then have adjusted it if I had wanted to. 
That is a really good idea is 38psi what i need to set it to to be safe or can i go a little lower ? What is a good shut off psi for i know i wont get any surging?

Maybe some of our experts here can tell us at what pressure we run the risk of a lean condition that can cause damage.
I will be using an FJO wide band which will shut the system down if it gets too lean. I am considering just hooking the fpss to a warning light only so I will see if the fuel pressure drops below what ever I have it set at.

We recommend that they be set at approximately 35psi. This seems to be a pretty safe number that normally doesn't cause any surging affect.
Terry, that is a pretty good idea to have it wired to a warning light to let you know what's going on without having to keep an eye on a gauge.
