Default Quick question regarding removal of fuel supply line

Hello,

I am adding the 3' of fuel line from the OEM FPR to the supply line to hopefully remedy my stumble issue until my rails arrive. For all intensive purposes; this is regarding the fuel system for a 2008 STI. I know years are similar but I'm balls deep trying to do this :/

Anyways... where the hose comes out of the FPR to the fuel supply line for the rails, it attaches to the line using a crimped piece that has a green in color sort of locking device. I cannot find a way to remove this so I can replace it with a longer line and clamp it down.

Any insight would be great. Replacing the OEM line with 3' of 5/16 fuel line. I do not want to damage the OEM piece just in case this causes more issues. The car has been sitting for almost 24hrs so not a whole lot of pressure in there.

Thank you

Corey

The green insert is part of the quick disconnect. Here's a long thread on how to do the fuel line mod:

For the quick disconnect I used a ball point pen cap that I cut/split length-wise into two pieces. You insert the pieces into the end 90 degrees offset of the notches in the green tab. Some folks can use the flat ends of cable ties to do the same thing. The mod also involves adjusting LC tables in the tune.

Here's what the connector looks like on the inside (and yes you can buy a tool if all else fails):

So this isn't necessarily a mechanical fix in and of itself? Any detrimental effects if I don't get some sort of tune right away?

I am not running boost as I am breaking in my new built motor. Just need it to be able to go highway speeds. No boost, no hard acceleration.

The pen worked! I didn't split it 100% and the thing came right off. Amazing trick thanks.

Also reporting that just adding the 3' of line did solve 90% of my stumble issue. AFR is stable, fuel supply stable, very minor stumble now. Just need to install the rails/fpr later and tune.

Thanks for the help
