APDTY 103931 Vertical Heat Sink for GM 6.5L Diesel PMD/FSD Fuel Pump Module (Allows Vertical Installation of Heat Sink to Release More Heat)

Brand New Heat Sink (Anodized Blue Billet Aluminum)
Fits All PMD/FSD Pump Mounted Drivers On Chevy / GMC 6.5L Diesel Engines
This is an upgraded heat sink that can be used in place of the existing heat sink. This heat sink is designed to mount vertically to capture more air for more cooling ability to the fuel injector pump mounted driver. Also this is made from premium 6061 aluminum and the blue color is an anodized coating that prevents corrosion. This item will bolt directly to the pump motor cover mounting holes and requires removal of the cover. The original factory wiring harness can still be used. This design also prevents overheating during idle as the vertical mount allows the heat to rise instead of the OE horizontal setup that allows the heat to trap under the PMD. We also sell a relocation kit, search APDTY 015224 for the relocation kit.
