I do not know if you can run a stock tec h40 carburetor with a pulse pump.
I do know I have pulsed many a carburetor and besides a very very simple float adjustment have had zero issues.
I will definitely be more mindful when I recommend a carb setup. Hope i didn’t steer you wrong on this one.
I would think a pulse pump running to the h40 carburetor on your manifold with the shroud drilled for the fuel line to go through would be an ok setup.
This way you can run an external tank and it will still get fuel. The throttle cable is the next hurdle.
It’s so much modifying when stock goes out the window as SparkWizard says your basically re-inventing the wheel.
