I having trouble undoing the quick release connector to the fuel pump. I'm using a special insert tool, but it's not working. Any suggestions? I've blown it out and sprayed it. Is there another way?

Thanks.

 

Finally got the right tool from Autozone, an OEM brand, $3.50, 2 pieces of plastic that fit in separately. Did the trick. 3/8" diamaeter
