Fitting Size:

Improved Racing has partnered with Marco Fluid Tech to bring you these high-performance electric gear oil circulation pumps. We tested several pumps ands chose Marco for their high flow efficiency relative to their size and weight, which makes them ideal for circulating fluid in performance automotive transmissions, differentials, and transfer cases.

These pumps are self-priming and can operate in the absence of fluid. They feature helical bronze gears which guarantee constant pressure, heavy duty cycles, and quiet operation.

In testing, this pump was able to pump SAE 30 weight oil at 25°C (77°F) at 1.45 GPM. A operating temps closer to 100°C, flow rates will be significantly higher, approaching 2 GPM.

I switched to this pump from a Tilton 40-525. I am using this pump in a transmission cooling application where it circulates fluid through a filter and cooler while the engine is shut off (Drag racing application). I was having problems with the tilton pumps leaking. Upon contacting Improved Racing they recommended this pump. I have been using it for about a month now. Its much quieter than the tilton was, the housing is all metal vs the plastic composite which I believe was part of my leaking issue. Its smaller, lighter and is actually providing improved cooling efficiency over my previous setup. The pump comes with fittings and is packaged well.

Thank you Michael and Improved Racing for your recommendation. I am very happy with this product.
