I put a check valve in parallel with the VW engine-driven fuel pump. The VW fuel pump will not flow fuel if the engine is not running. The electric backup fuel pump cannot push fuel through the VW fuel pump. So, had to put the check valve in parallel with the VW fuel pump to get fuel to the carb for starting.

Remove the check valve! I don’t have one on my fuel system, it will just cause problems.

I would like to say thank you to the entire KR community and especially, Luis
with regards to getting my plane started.

I now have the engine running on all 4 cylinders. - it does sound nice.

The caveat right now is that I am taking the fuel straight to the throttle body.

Still having issues with the vacuum operated check valve.

Thanks
