I don't think I have an oil pump issue but am definitely planning to add the filter between the HEUI pump and the head and would like to also add bypass oil filtration. I'll likely do my oil changes at 7500 miles for now, then likely extend that if I do install a bypass system.
Relative to the oil pump issue, shouldn't CAT be able to tell us what oil pump was used in the motor by the serial number? If you already have the revised style pump, no need to change it unless you are actually having a low oil pressure issue.
Now, back to ECO hubs......the exhaust brake info was relevant as I think it mitigates (mostly) one of my concerns with the eco hubs. Oil pumps and such have nothing to do with the hubs
Happy Holidays everyone!
