I couldn't tell you the maximum PSI it can flow or sustain but I can tell you that the specification for fuel rail pressure on the 2.0 in the Sonata and Santa Fe is 3.0~15.0MPa (30.6~153.0kgf/cm²,435.1~2175.6psi) while the Veloster N is supposed to have 4.0~25.0MPa(40.9~255.0kgf/cm²,580.1~3626psi).Well is this pump higher flow than stock? If it is, by how much? If it's close I will keep it but if it isn't I am returning it. Is there any possible way we can get flow rates on the different part numbers? This would be great if we could.
Judging solely based on that, the pump from the Sonata & Santa Fe theoretically should not be able to out perform the Veloster N pump. However if the cam lobe on the Veloster is a larger / different shape than the others and can overdrive that pump, it stands to reason that one of those pumps on a VN could produce more pressure throughout the RPM range.
