AEM fuel regulator
 

got a fuel pressure regulator but im not sure about what the p.s.i. is......my buddy said that i should go and get a gauge that will let me know the p.s.i.....or does the reg. already come set at the right p.s.i.

you'll need a guage to know what the aem is set at.

^Yeah...to know for sure you'll need a gauge. Even if it does come preset (which I kind of doubt since they have no idea what kind of motor or mods you've got), it's just an extra little safety precaution.

k thanks

went to www.aempower.com and they said that the regs. come set to 40 psi
