monaro fuel line disconect tool

[guru_1071]

I'm helping a lad at work swop the leaky front to rear main fuel line on his 2005 CV8 monaro

can anyone advise if this tool is the one we need to pop apart the couplings on the ends of the steel fuel line?

or if not, any advice as the tool we need

many thanks

that looks like one that worked on mine - if stuck I could lend one..

If desperate a pen lid of a marker cut down the centre then slid over the hose and pushed hard in to the connector. Works a treat.
