Abstract
A quick connect assembly for a fuel pump outlet line and a fuel tank line outlet with a flexible grommet received in a housing connected to one of the lines. The other line is received in a central hole through the grommet. A cover overlies the grommet and is urged onto the housing by a compression spring. In use, pressurized fuel is received in an annular groove in the grommet and urges it into sealing engagement with both the line received therein and the housing.
