5.7 marine power carb not sure about the year what size presume cap? 7.5 is what's on there sound right? Thanks
 
Are you asking about a Closed Cooling system Heat Exchanger expansion tank pressure cap?
If so, I believe that 7.5 psi would be on the low side.
 
7 PSI on the HX cap is pretty common thru the mid 90's....the newer EFI engines usually have 16 PSI caps...
