Once the fuel water separator looked full I reconnected the line to the gas tank. And, then I pumped gas from the separator into the motor using the squeeze bulb located on the line between the motor and the separator. Yes! it worked fine.

I found this filter is nice to me. Though it is nice to me it seemed to be heavy-duty, compact, and easy to view. But it was unusable for my application due to the factory-installed plugs. Instead of sending all fittings with two plugs and two barbs separately works in a bag, they sent the barbs in a bag and the plugs preinstalled. As the plugs were installed so tight that they could not be removed which used over 250ft-lbs of torque and they did not even budge. So, I sent one back and got a replacement that had the same issue. When mounted, if you need left in and left out you will be ok, but if you need right in or right out or an opposite side in or out then you might buy another filter! So you can return both and go with the MarPac system, which has worked flawlessly and was easy to install. As I just got installed a week ago. And, do know that the hose adapters that come with the filter I received are ⅜ inches. I am using a 5/16” fuel line, so I had to buy different adapters, but I knew that in advance and bought them at the same time as the filter. So I tighten the hose adapters several times because they will leak if you don’t. And, I had to make a bracket, but no big deal, just watch where you mount it so it does not get hit with tires, mower deck, lift arms, etc. I scaled it on my Kabota BX series tractor. Because it uses two cheap in-line filters that freeze almost every winter as a reason for water condensation. Now I can see and drain the water off at the same time.

And, I found the original fuel filter canisters were decaying and leaking. So, I tried to remove them the metal was collapsing and twisting.

If you want to replace your fuel filter, it’s a good idea to replace this at least once a year. Before installing you can fill it gas as much as you can.  And, pour old gas into a clear glass jar and let it sit for a couple of days to see if you have water in your fuel-especially if you’re using ethanol fuel. I have never had a boat before that required a fuel filter like this one. So, I just bought the boat that was used last year. And, the first time out this year, the engine started but didn’t stay running long. Then it wouldn’t start again. In this situation, I  took the old filter off and put this on. And, now it runs as great again. It feels always nice to use name-brand parts. So, I get a great price and fast shipping on this filter.
