fuel return line connector?

I think my fuel pump is dying, the car has been gutless a few times and has sputtered to a stop a few times too.

I'm doing Pete's diagnostic procedure and sometimes I have 30 psi, sometimes 24 psi at the fuel rail. I want to disconnect the return line from the bottom but have no idea how to disconnect the connector.

Can someone tell me the trick?

Down where the line connects to the return line back to the tank, I think there is a plastic clip that goes into slots in the connector end that hold the line in place by virtue of it flange.

that's correct... I did this a few months back. Just below the oil filter the 2 flexible fuel lines connect to the steel lines. There is a C like clip that snaps into the connectors of the Flexible and steel lines. Once the C clip is removed the lines should separate fairly easy. FYI... there is a tiny o-ring in the flexible line connector that can easily get damaged and will cause a fuel leak after reassembly and under pressure.

good luck!
