Thread: Cannot separate hard line from accumulator

    My VIN:    1890

    I squeezed some 0.5" conduit to make a snugly-fitting extension to my 3/8" ratchet:

    I was then able to use that with the 19mm flared crowsfoot to loosen the flexible line fitting, while holding down the accumulator with a 17mm wrench, with a temporary pipe extension. The helpful thing here is that the flared crowsfoot, and the snug extension, can hang by themselves from the fitting, while you get ready with the other wrench. After removing that fitting, I was able to remove the hard-line fitting using a 17mm 'normal' crowsfoot (with the extension ratchet), while holding the accumulator with a 14mm wrench, with the temporary extension.

    However, I'm still stuck with the ferrule that won't come loose from the fitting:

    Although I can attach the fitting to the new accumulator, I'm a little concerned that unless I unstick the ferrule to allow it to reseat into the fitting and line, that I will have leaks. Any thoughts?

    Donít worry about the ferrule fitting. That joint will remain leak free. Just retighten the line B-nut after you have it all back in place.

    You do have to really crank on that fitting because it is steel, not brass to get it to be leaktight when you re-assemble. When tightening that fitting you are deforming that ferrule to make the joint leaktight.

    +1. When you get it all back together, tightened, and fuel primed in the system, you will want to check that fitting and all the others for leaks, weeping, etc. while the car is still elevated.

    A lift is awesome to have, but I did all my underside work (including gearbox R&R) with jack stands.

    Glad you got it off. The accumulator is up there on the list of worst jobs because of limited access. The homemade ratchet extension and crows feet were the ticket for me.

    I did spend literally hours trying to pull the fitting/ferrule from the hard line, so that now the ferrule spins freely (along with the fitting), on the hard line. That's why I'm concerned about getting a tight connection again. I will certainly pressure the system up while I have it jacked up so that I can check thoroughly for leaks. I'll see what happens.

    Thanks,
    Robert
