I let my car go well pass the 1/8 mark all the time with no issues. As the others have said, it could be just an improperly installed pump or the fuel canister wasn't aligned properly so the gauge is off. The latter is a very common noob mistake. There is an arrow on the outside of the fuel canister (it may be hidden by the mounting ring). This arrow needs to point straight up to the sky, perpendicular to the ground.

The only issue with the Neon/SRT-4 model Walbro 255 I know of is a pressed metal piece on the pump falling out. I've encountered the pin issue twice already in the last three years.
