I have a used FPSS and I have someone trying to buy it. How the heck do I tell if its a carb or EFI switch? Or does it matter. I know the pressures are different between the two. It does have the adjuster on it under this rubber black piece. Any input would be awesome. Thanks in advance

 

post a pic someone should be able to tell you. a carb switch probably wont have newer quick-connect fittings, more something for line + clamp.

 

It has the threads to screw in on the bottom. And 2 screws that you attach the wires to. And thats pretty much it.

 

carb kits don't use them

 

Carb kits done use what? They sell 2 different models, one for carb w/ a lower PSI. And one for EFT w/ a higher PSI

 

show me a kit that has one in it..........

then you can call me a liar

 

I'm not talking about kits, I'm saying they sell them for both. Here ya go, enjoy.

dumbest thing i've ever seen.... just a way to scam money from people who don't know any better

so ok... i lied

 

so to answer the question... yes it matters , hugely

using a carb switch on efi would be pointless, since it would cutoff nitrous at about 15 psi, when it should cut it off at about 35 or under

same thing the other way, pointless, since it would always be in 'safe" range for a carb car if you used an efi switch

if you knew the brand and part number it would easy, but doubt there are any markings on it at all

 

Its cool man, your not a lier lol. Thanks for the help though.

Unfortunatly, there isn't any markings on it. Sucks to, cause I would have it sold if I knew what it was for. Doh.
