    Default Getting the fuel pump gasket to stay where it belongs?

    Hey all, I'm in the process of changing out the fuel pump on my 97 Tahoe 5.7l 4 door. I can't seem to get the gasket to stay seated, once I tap the lock ring into place part of the gasket is sticking out. Any tips ???

    Did you get a new one or are you trying to re-use the old one?

    Sounds like you might be over-tightening the fasteners. Check the torque spec and use a torque wrench to install the fasteners.
