Re: Fuel System Vent?

A thought on venting: you have the problem worse with the tank full. When the tank is full there is little air and when a small amount of fuel is used that empty space expands say 100% and a high vacuum is created.
With the tank near empty and the same amount of fuel used the empty space expands say 10% and a much lower vacuum is created. EZ to test, when the problem occurs remove the gas cap, you should hear a whoosh air going in and the starvation problem should stop.

Then again when a tank is filled the crud is stirred up.

Good Luck Sherlock
