Hello Berryman CS, I bought an intake valve and combustion chamber cleaning kit. The black plastic orifice at the can end leaked so badly that half of the cleaner did not make it into the pvc tubing and made quite a mess in the engine bay.  The box was unopened and undamaged. This looks like a manufacturing defect. Can you either send me a new kit or a refund? I bought it at Walmart but they won't take it back.
