If it is caused by a leaking fuel cap, I suppose completely covering both caps
with shipping tape would make them airtight. This is obviously a Band-Aid
solution, but if it eliminated the uneven flow it would provide further
evidence the fuel caps are indeed at fault.

I think you have the right idea. At least it couldn't hurt! I will upgrade
mine as well.
