Fuel pressure sender recomendation

Hello forum members,

I am looking to buy a fuel pressure sender for my newly installed MGL EMS-1 I'm using with my new 912ULS. They recommend the UMA 7 psi sender.  However, my question is whether 7 psi is enough since per the OM for the 912 it indicates that the max pressure is 7.26 psi. Ok, it's pretty close but a sensor should be somewhat higher than what you are trying to measure so what are people using out there? or is this sensor just fine?
