    API suggests installing inside the cabin to keep it out of the heat. I didnít want a fuel pump inside so itís mounted on the lower right side of the firewall inside a sheet metal box thatís interior is cooled by a blast tube. The front is secured by a couple of quarter turn fasteners. It works great. No hot start issues.

    Are you using their fuel filter? I didn’t and I wonder if I should. Fuel goes through a Steve’s gascolator before the high pressure pump so hopefully that’s good enough. I’ll add a pump on indicator light in the panel this winter. I forget to use the pump for takeoff and landing more often than not.

    Difficult to see. The Whelan pump is located just under, slightly ahead and outboard of the fuel selector.

    Don’t forget to plan for a fuel pressure gauge, which means putting a sender unit in the fuel line after the mechanical pump. I didn’t do one initially and added it later. It would have been easier to install at the start.
