Flowkooler High Flow pump for the 1964-1970 Buick, Jeep "Dauntless" and Olds motors has a CNC machined billet impeller is designed with an increased vane count and a reduced plate-to-impeller clearance.  This design achieves greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps. The color is due to Type II Class II military grade anodize surface coating which protects against corrosive fluids.  The pump originally had a die stamped plug plate like the OE but due to the higher pressures, we re-designed the plug and now machine a 6061 billet aluminum into a press fit plug that will never come out.

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Reliable, Well-Designed Sewer Hose Kit That Just Works
Style: 15' Rhino Sewer Hose
This Camco RhinoFLEX 15-ft RV sewer hose kit is another example of why I continue to buy Camco products. Everything about it feels well thought out, solidly constructed, and designed specifically for real RV use. The hose is flexible yet durable, connects easily, and holds its shape without feeling flimsy or cheap. The clear elbow fitting with the removable 4-in-1 adapter is especially useful. Being able to visually confirm when the tank is fully drained adds peace of mind and takes the guesswork out of the dumping process. Connections are secure, leak-free, and quick to set up and break down at the campsite. After using it multiple times, I can say this kit simply works the way it should. It’s dependable, easy to handle, and offers excellent value for the quality you get. I would absolutely recommend this sewer hose kit to any RV owner looking for a reliable, no-nonsense solution that performs every time.

Clear elbow not detachable
Style: 15' Rhino Sewer Hose
Sewer hose is fine except the clear elbow is permanently attached and no removable. Also shipped via USPS vs. UPS. USPS couldn't/wouldn't deliver so had to go to the Post office to pick it up.

There have to be other places to save on your camping budget
Style: 15' Rhino Sewer Hose
After 5 years of regular use with my original Camco RhinoFLEX sewer hose, I decided to proactively get another one and retire the OG to the inside of the bumper to keep as an emergency use hose. Did I consider purchasing other brands and hoses to save a few $$$? Yes I did. Then I thought about never having to clean up a stinky black tank mess and promptly bought another one. If it ain't broke - or hasn't broke after five years of use - then don't fix it, and by that I mean don't overthink it. RhinoFLEX FTW.
