Setting up to run external oil pump on Dt466. What GPM pump should I run? Going to use a Prince gear pump series 25A. Thanks

When on a IH 466 is it a must to change to the external pump... Cubic inch?? Rpm?? Compared to the 1 1/8 stock pump?

I'm not sure but I've been told by many it is worth it to go this way. I'm sure there are many opinions and I just went with the one I bought my engine parts through.

We run 40gpm (two 20 gpm pumps) with 90-120 psi on both of are superfarms. We have aviad external pumps 4 stages two for engine one for turbo and one for fuel.

I should also mention that I am going to still run the engine's oil pressure regulator with the heavier spring that should put the oil pressure somewhere around 80-90 psi. I guess my consern is with the large volume of oil can the regulator handle it and will it handle the high pressure of the pump?

I know that the aviad pumps have a built in preasure regulator. Not sure about ur gear pump but ur regulator should handle it ok.

I would probably act upon the advice given by your engine parts supplier as to what pump setup to use. Will probably save you a lot of hassle.

Where can u get this spring?

Just don't get the pump to big I had a 3 stage Peterson and couldn't keep bearings in the engine the problem ended up being the pump was pumping way to much oil and with the built in bypasses it was foaming the oil inside the pump .The fix after a couple thousand dollars and sending the pump back to peterson a couple of times was to plug the built in bypass and use a external bypass with a 3/4 return back to the pan no more problems .Un less I had a 3 turbo super stock I wouldn't give a nickle for another one
