- - Replaced fuel sending unit (https://forums.wmpdevserver1.com/community/showthread.php?t=20076)

I had an interesting time getting the new fuel lines and new filter primed. I first tried the squeeze bulb, but that was futile. It doesn't pump air. I couldn't get the system to prime. So then I broke the fuel line before the squeeze bulb, put a short line into a container of fuel, and pumped it up. Started the engine, got it running about 1000 RPM, then quickly switched the fuel line to the boat installed system. It never even hiccuped! Apparently the engine fuel pump is pumping fast enough to prime all those empty lines and even the new fuel filter-- Whatever, it worked and I was able to switch tanks with the selector valve while the engine was running. I am ready! 40 gallons in two saddle tanks.

Used the engine fuel pump to prime the new lines and new filter all the way to both fuel tanks. Worked! Started with a fuel line in a gas can and then switched it to the boat system while the motor was running. Never a hiccup!

Well, I went looking for the cause of my non-functioning fuel gauge,(like the repair was Kryptonite, been putting it off for 6 months). Turned the key on and viola, the fuel gauge works again... So now what? I tell you what , I gave the eurethane a good seal coat of Awlcare and thanked heaven above for the assist.. You see, as a bonehead, I did not take into consideration the placement of the sending unit in relation to the baitwell. It is all undr the floor hatch which has a console, t-top, well you get the picture. It will be a small PITA to replace the sending unit, so I am really happy it started working again. But the the question does arise, WHY ? What is making it work intermittently? Loose connection?

My guess is lose wire! But I hate gauges and they never seem to work, so I learnecd were and when I would run out and always went out with a full tank! Even when I sold my Sea Ox it had 110 gal gas in it!!

But I will need to either add one gauge and a switch or two gauges on the dash somewhere. This boat apparently never had fuel gauges. There was a piece of round doweling in the boat, and I would bet that is what the fisherman used for their fuel level.

BTW, I dumped both tanks into plastic gas containers and poured about 7 gallons of that stuff into my Durango gas tank (which had 3/4 of good gas). I saw several discussion comments wherein boat experts suggested that because a car's fuel filters are really good, and because the dilution of that much good gas will make that old gas and oil mixture harmless.

I drove the Durango today and noticed nothing different.

At the end of every season I always empty my tank as much as possible and put in my Lawn Mowers, Snow Blowers, whatever... anything but the boat engine. I've never had a problem with any of the gas, but why take the chance in my boat's engine?

Befor I replaced my sending units .I made a simple old school measureing stick.I graduated from a empty tank and marcked it off at 5 gals 7 1/2 gals and so on till full.The sending units work fine now but they can't be as accurate as my stick
