Sampling that there is no bubbles — some confusion.
Replace the return line on the front of the ip with clear tubing. With the engine starting and running you should not see any bubbles flowing. If you do there is a leak, but instead of fuel leaking out, air is getting sucked in. The bubbles disturb the injection pump operation.
