Ok hopefully I can explain this so you understand my problem. We got the system up and running and the return fuel line is in the back of the tank near the top.but after several minutes of running I had fuel rising up out of the fuel filler and all over the floor! The car is sitting on jack stands in the rear and on the floor in the front and the fuel tanks are 3/4 full. I know that now there is no place for air to escape with the car at this angle and if it was on level ground there would be no issue. But what happens when the owner fills the tanks to the top ? There will be no place for air or pressure if you please to escape! I'm stumped on this one ,anyone go through this that has an answer to help me out on this one.
