Look to the current threads about rack dampeners for your cold start/run problem first.

The dampener works nicely when new but many a tech goes overboard on the adjustment. The intent is to just touch the rack with the tip of the spring loaded screw. If the screw applies too much pressure the car will die on cold starting or under the influence of the P/S right after start up.

I don't think you leak at the tank will cause this problem. The low pressure fuel in the pump cavity (which is necessary) is checked by the feed pump from backing down the system. Besides if there is air in the pump cavity you probably would find it hard to start and pick up cylinders slowly until it ran fine.

Thanks for the complement.
