Need help quick!!!!!

I installed my new pumps lastnight. Took my time to make sure everything was hooked up right. I know why my Gas gauge isn't working, but my fuel pressure gauge isn't working now. I hooked up my diablo to the car to check the fuel pressure and at idle the car was only pushing 14psi????? What in the world is wrong? These pumps I ordered are suppose to be the exact pumps that I am taking out so I shouldn't need a tune for them. These are the walbro 255lph pumps. I can't drive the car anywhere without fear of messing something up. Somebody please give me some ideas. I plan on dropping the gas tank again when I get off work to see if my float got stuck or wedged without me knowing it lastnight when I reinstalled everything.

Make sure you didnt pinch the line when you lifted the tank back into place. As far as the guage, it hooks up to a valve at the end of one of your fuel rails...make sure you have a good connection
