Fuel pressure?

^^ the 370z and 350z fuel pump assembly, while very different in appearance and construction, have essentially indentical features. I would not say that one is any better than the other. 350z owners have less issues with fuel starvation in high load turns but I think that is more related to the fuel tank dimensions since the fuel pump assemblies are so alike. The tanks are similar overall shapes, but the dimensions are rather different.

I am not sure at this point which G37s use the 350z assembly. I dont know if its related to sedan versus coupe, or build date, or what.

The easiest way I can describe how to tell which assembly a G has is to remove it from the tank and look. The 350z unit has all its passage ways and plumbing molded into the housing, so you cannot clearly see how it is plumbed. The 370z unit has all external plumbing, so you will see black nylon hoses connecting the components within it.
