Fuel leak from ring
Hi, my fuel pump **** out on me.
replaced the fuel pump, and new gasket and the pump started leaking.
i couldnt get the ring back off, so i cut it and got yet another ring and gasket.
STILL leaks even after replacing the entire ring and gasket
i have scoured the internet about this issue and cant get a definitive answer to my problem
i confirmed it is not leaking from the siphon or the line connecting to it
it does not leak fuel at about 75% but i put in an extra 3 and it started leaking again. Let it sit overnight and it filled up a paper towel
is it a matter of me needing to tighten more?
should i be using a silicone grease on the fittings and gaskets before installing the pump?

Confirm that the new o-ring is the same thickness as the old. Perhaps try installing the old o-ring and when you do, coat it in some sil-glyde from Napa. This will help prevent the o-ring from binding and possibly tearing. Also, do you have the correct special service tool for installing and removing the lock ring?
When you cut the lock ring, ensure that you didn't cut into the plastic threads on the tank. If you cut too deeply, fuel could leak out where you made your cut. Do not overtighten the lock ring as well. You'll hear it creak and seat. There's no reason you should have had to cut it off on the second removal. It should come off easily. When installing the lock ring, I like to spray a light amount if white lithium grease on the threads of the lock ring. It helps lubricate it as you tighten it and helps prevent the plastic to plastic binding.
I would also look at the feed and return lines that connect to the pump assembly. There will be an o-ring in each that will help seal them to the lines on the tank. Ensure you didn't roll and o-ring or cut it. I also use sil-glyde on the fittings on the tank before I install the lines. That or a little silicone spray. Helps prevent damage to the o-rings in the fittings on the fuel lines. I'll even go as far as spraying a small amount of silicone spray into the line to lubricate the o-rings.
