This is a caution for anyone installing a new sending unit. A few months ago, I went to a lot of trouble to install a new fuel sending unit in my diesel tank. A trip in December revealed that the fuel gauge always registered full. I replaced the gauge but still had the problem. Finally I decided that the new VDO sender was defective, so I ordered another. The new one came with a small sticker that said to remove the safety pin. Sure enough, the new one I had previously installed did not have this small instruction sticker, so I did not know to pull the tiny pin. Now the original one works and I have a spare sender and gauge.
