Just like the title says. I got a fuel flow sensor and a fuel level sensor to add to my boat a couple of weeks ago. The fuel flow sensor works great and was recognized in the device list. However, the fuel level is not there.

When I hooked up the network, I got the starter kit and have 4 tees in place now. One to the battery, one to the HDS, one to the fuel flow sensor and one to the fuel level sensor. The sensor was hooked up to my sending unit and the analog fuel gauge was disconnected.

Any ideas?

Also, I have been hearing more that people like the fuel flow sensor to tell how much fuel is left over using the level sensor. With fuel prices the way they are, I know I am not going to be topping the tank off and know I can do a partial fill, but now I just have to figure out how is the best way to empty my tank and refill to get an accurate level to begin with.

Thanks for any and all help.

all devices are NEMA 2000 compatable I assume...

Yes. The sensors were from Lowarance and said they would hook up to the HDS unit and I got the Starter kit to get the whole network setup.

Multi-level programming is required in order for any MFD to recognize that FLUID level sensor. Because it is a FLUID level sensor, capable of being installed in fuel, water, oil and other tanks, one of the steps is to program what kind of FLUID you are measuring. In addition, the "instance" of the tank must be set ("0" for tank #1 and "1" for tank #2 in my case.) Then, setting the capacity of the tank in gallons is required.

All of the foregoing is from my memory as I watched a professional set up two EP-65R's in my two tanks using a Lowrance head unit (temporarily added to my Raymarine SeaTalkng cabling system). If you've already done all that, my apologies.

Pez is probably right. Can you select the sensor under Network / Devices? I think it's there that you would set the parameters of the sensor.

The problem is that is does not show up under my devices like the flow sensor does. Under engine, I did set up the tank for fuel and put in the gallons, but I guess that is separate.

I called Lowarance the other day and after being on hold for twenty min, the guy said he had to transfer me to another dept and then just sent me back to the main menu. Guess he did not know and made it someone else's problem. Lol

Try running the auto configure from the network menu.

You're really pushing my buttons, so I went completely over the top, and leaned over to my bookshelf, pulled the EP-65R instructions out of my marine electronics folder, and read the fuel set-up instructions on page 25. It's all there in excruciating detail.

Pez, I truly appreciate your help as I do others. I am not one of these that do not do my homework before posting a simple problem on a message board for others to do all the leg work with me.

I have that instruction and the one for the EP-60R on my desktop. The detail you provide on page 25 are great if you are using a digital gauge. I am connecting it to my HDS, and at the bottom 1/3 of that instruction manual is for the display unit, but the menus are different than the HDS.

Lakensea - I did run the auto configure with no joy, that is what is really got me confused. I am going to give Lowrance a call back tomorrow and see what the can figure out.

Again, I appreciate everyones help. I will post an update when/if I get it up and going.

So this issue was buggin the crap out of me. I swapped the wires at the network Tees for the fuel flow and fuel level sensor and all of a sudden it is recognized.

Thanks for all the help.

so at the end did you have a bad tee or just in the wrong part of the tee???
