Had a similar situation a few years back.

Long story, turned out to be a combination of excess rain, a recessed vent cap and bad luck.

Known problem with fuel fill. OEM sent me updated part for free. No problems since

What clear canister?
You do not reuse coalescing fuel filters. You replace.

Suggest going to a Racor style filter with a drain on the bottom. No guessing if you have water

Any update? It happened to me as well. Water entered the gas tank. Any advice would be appreciated. Please. Thanks in advance. I was searching for this https://writinguniverse.com/admission-essay-writing-service/ website online because I want to hire an essay writer from an online essay writing service and when I was searching for it online, I found this page where I found a lot of reviews which is very useful for me.
Any update?
