Replaced fuel sending unit

[spareparts]

I've been using the wema senders lately, I can't say they are any better(time will tell) but they sure are easier to install. Measure the tank, order the sender that's the right length and install. No bending or moving the float around. As far as testing them, I ground the pink wire to the ground wire on the sender, if the gauge buries itself, then its most likely the sender. If the gauge doesn't move, check the wires, power and ground to the gauge, then ground the pink wire at the gauge, if the gauge doesn't move, the gauge is bad. If you want to get real fancy, Lavorsi sells a sender that once its installed, you empty the tank(leave a couple gallons just in case), turn the screw on the pot till the gauge reads empty, then fill the tank and set the other pot till the gauge reads full. Regardless of what kind of gauge or sender you have, its only going to so accurate due to the design of most boat tanks

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!!
