Are you sure you have the correct pump? Are you sure you have the correct voltage at the pump? Have you checked the pressure?

Sounds like the new pump may be overheating the fuel causing excessive vaporization, and pressure in the tank.

You attach a fuel pressure test gauge to the Schrader valve on the hard line that connects to the back of the passenger side fuel rail.

In fact, Shoebox told you to check the pressure last time you asked a question about the fuel pump:

Guess you ignored his advice.

did not ignore my fule pump was over heating thats y i didnt do that

So your old fuel pump was overheating.... and now there is evidence that your new fuel pump is overheating? Is that correct?

But you haven't checked the fuel pressure. Have you checked the voltage available at the fuel pump harness connector over the rear axle?

Are you sure the air was rushing out and not in?
