Sealing the sending unit

[1983lux]

Any tips on stopping leaks with a very full tank from the sending unit? I replaced the rubber ring and did the best I could to close it up tight without the proper tool using a screwdriver and tapping it. I feel the leak is coming from around the electrical plugs on the unit itself. Tried using Seal-all but it doesn’t seem to hold up for long.

Any tricks out there?

Thanks!

Can you post a picture of the tank and the ring? I would only use an original seal, as this is a very special shape for the original sensor. If it is leaking around the electrical parts, it is not the fault of the seal and you should replace the sensor. I have a spare if you can't find one. You could replace the sensor with a new design, if all else fails, but it is a lot of work.

Interesting! Reading your threads, I’m actually also planning to install this 4 in 1 gauge in the place of the stock fuel gauge.

I have a cb900 tach with a much nicer face than my original, but it doesn’t have the temp gauge like the GL one, so was thinking to replace my already faded and ugly fuel gauge with this aftermarket unit:

Maybe I need to change the sending unit for that to work regardless of the leak

I have tried two of those 4in1 Chinese gauges and both were no good. Try a different model. Faria makes high quality gauges.

When you buy the gauge, consider the sending units you will need to match them. There are two common specs, the USA and the European. There are a few gauges that work with several different standards, but most are specific to only one standard. I used resistors and an ohm meter to determine the exact sensors I would need. The results of my research led me to buy USA standard sensors. The range of the gauge will also affect which sensor you choose. Some of the temp gauges only go up to 220 degrees and I would find one that goes to 250. My oil pressure goes up to 100 psi, but I would prefer one that has a max of 80 psi.

Most of the Faria gauges require USA standard sensors, but there are a few for the European standard.

Sensors for the Faria GF0036B:
1. Oil Pressure: 10-184ohms
2. Fuel Level: 0-190 ohms (E-F) for fuel level meter
3. Water Temp: 320-22ohms

Very cool indeed !

I haven't tried VDO gauges but they are probably high quality because Porsche used them. This one caught my attention and I think it would go great with the matching clock. I would mount the clock on the blank where the original fuel pump was mounted. VDO also sells sensors that match the gauges.

My sending unit was leaking where the connectors for the gauge go through. I used JB Weld to seal it and it's lasted three years.

Mine is also leaking at connector, tried some JB weld will test tomorrow.
