Product received was 100% correct

I was in a pinch looking for a water pump for a Carrier unit with a Kubota engine. The Carrier pump is on a long back order and quite expensive. WDPART came through with the correct part at a very reasonable price. Will definitely order from them again.

Replacement 29-70183-00SV Water Pump for Kubota D1105 CT 3.69 Diesel Engine

Great replacement Voltage regulator

After troubleshooting that my voltage regulator on my 2009 Piaggio MP3250, was bad........I ordered this one and it fixed my issue. Mine was reading over 20v! It is supposed to be 14.6 or below. This was a perfect fit and worked immediately.
