I'm hoping that this is a grounding issue. > What do I need to do to properly ground the sending unit? I don't think I'd ground it to the antenna, as that leads inside your radio. It probably won't hurt anything, but why take that chance. Grounding it on any good ground should work. The body of the fuel sender needs to be well grounded. Normally it is by virtue of being bolted to the gas tank. Touch the wire to a spot of bare metal on the gas tank. The needle should go to full. If it doesn't, the gas tank is not grounded. It should be grounded to the body by way of the 4 clamps around its edges. If it isn't, check the 4 bolts and see if they are grounded, then the 4 clamps. Let the clamps bite into the tank a bit so that they make good contact. Once the tank is grounded touch the wire to the sender body. If it is not grounded then loosen and tighten its bolts (don't overtighten) intil they make good contact. Once the sensor body is well grounded the gauge should work. If not, send me the sensor and I can fix it for you, but it would surprise me if a new sensor had this problem. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
