Number of crimps will depend on the size of the cable, if you are able to look up AC 43.13-1B starting at 7-140 through 7-148 it will give you all the data you need to understand cable designs and complete the job.

I am replacing one of my landing gear safety cables on my model IV. The original cable has a copper nicopress sleeve. Are these special aircraft grade sleeves or can I use the aluminum sleeves from the local hardware store.. Aircraft Spruce sells both a copper and what looks as if an aluminum sleeve. My second question relates to the swaging tool. The swaging tool I have access to leaves a pretty large crimp and on such a small sleeve I could only get one crimp. I'm guessing that a smaller swaging tool, which would allow me to place a couple of crimps on the sleeve, would be much more desirable. Any comments would be helpful.

The 3/32" cables we use on the Model IV is swaged with a single crimp. Larger cables will use a second crimp. Think it is a factor of the force needed for the crimp. A large cable using a single wide crimp would require more pressure than could be achieved with a hand crimper. I agree that the recommended crimp is the nickel plated one, though I have used the solid copper non plated.

Specifically, my header tank fuel level (I've installed a sensor to monitor its level) occasionally drops. The lowest I've seen it drop so far is to 50% of full (after which I decided to land). A couple of other times, it dropped to 75% and then filled again. I think this might be happening when the wing tanks are less than full, but my impression is that they were by no means empty. Is this normal? Is there anyway I can stop this from happening? It sure doesn't feel comfortable to fly in this way. My header tank is 3.5 gals (13 litres) and is located behind the seat. I have two wing tanks which feed into the header tank. All my fuel lines are flexible. I've been keeping the header tank breather valve closed. The wing tanks each have a breather tube on the tank cap which faces into the wind. Any suggestions as to how to improve things would be greatly appreciated!
