Fuel filter quick disconnect tool
thingiverse
When I couldn't get my regular quick disconnect tools to release the fuel filter on my 02 Tahoe I made my own and here it is. You will still need something rigid to put behind it and push on it. I had something laying around that worked. I suppose your fingers may be able to get it. I printed the tool in taulman 618 for strength and flexibility. PLA or maybe ABS could make the other tool you may need to push them both in to release it. I also used a drill to remove some of the inner imperfections on the tool so it would fit better and still be thick.
