G'day,

I am posting the following for information purposes only; I am not suggesting, recommending, commending, or anythinging the Melling
high flow pump P/N M-22-FHV.

I wanted to find out how much oil it flowed so I called Melling Technical Support and was advised that at idle (700-800 rpm) the
pump would deliver 3.25 GPM with the bypass set at 58 psi. The bypass could be set higher at 65 psi. The tech rep noted at 5000 rpm
their pump would deliver around 7 GPM and the OEM pump around 3.

Regards,
Rob M.

Thanks for the info, I installed one during my rebuild based on recommendation. Good to know the specs.
