Sorry for what may be a stupid question. I've been searching for a proper image of the mechanical fuel pump for a 534 SD engine on gasoline, something found in the AMT C Series kit. I'm running the kit air compressor and am ASSUMING that there should be a mechanical fuel pump on the left side of the timing cover behind it. All of the Holley carbs I have seen on this engine have a bowl feed on the left. I have yet to find a picture that shows either a pump or even a hole in the cover where it would bolt on. I realize that it would be hidden by the compressor, but I have yet to see an actual fuel pump on the 534 SD engine. Sooooo...where's the fuel pump SUPPOSED to be located? Did I just spend a bunch of time searching for a mechanical pump when the truck actually used an electric unit paired with tank switching valves? I add ridiculous detail, so this is kind of important to completing the engine for me. Thanks for looking...(Despite spending my career as a Tech on cars and light trucks, I'm embarassed to be asking a question like this...but I'm sure there will be more!)
