Oil is the lifeblood of an engine, remove it from one while it’s running – even for a short time – and catastrophic results ensue. For an engine to have proper oil delivery, it must first have several things. First, the pump must have a good supply of oil at the pickup or inlet, and it must also have the capacity to pump enough oil to fill all of the inherent “voids” like bearing and lifter clearances in the engine in order to develop pressure. Peterson Fluid Systems has made engine oil deliver their mission, and they are leaders in that realm.

We spoke to Pat Haberkorn, about some of the improvements they have made to their oil pumps, and he was happy to tell us, “We have been working on an improved bypass design to make our pumps more efficient. We’ve been using the same design –which great, but we’re always trying to improve the product.”

The new bypass design delivers more adjustability and oil pressure control, allowing the end user to better supply their engines. That prompted us to ask, ‘what kind of changes?’ Pat let us know, “The main change is how the oil will circulate around the bypass, giving much better pressure adjustability. This means oil pressure can be adjusted to be higher at idle, and lower at wide-open throttle, which helps the enthusiast, because every engine has different needs.”

This newly redesigned pump will benefit everyone form four-cylinder circle track guys, all the way up to those running a 40 gallon a minute diesel puller. And if you want to improve your engine’s external oiling system, check out Peterson Fluid Systems for yourself.
