Hopefully I made them small enough.

Thanks for everyone's input on the issue I was having with my VW powered Kolb MKIIIC. You may not remember but I had a ammeter that started fluttering from -20 amps to + 20 amps. Turns out it was the primary fuel pump. Since it just started doing it after 12 years it was likely it was in short failure mode. About seven years ago I replaced the Faucet back up fuel pump when it stopped without warning but it was just a back up pump so no big deal. The new replacement pump is a Carter automotive inline pump. This pump doesn't allow fuel to pass through it when turned off so I had to re plumb my fuel system to put the pumps in parallel with a check valve on the Faucet pump. Any way it is fixed. Now I need to go back and undo some of the changes I did to track down the problem. In the process I also changed the battery to one of the new Lithium batteries like Aircraft Spruce sells called AeroVoltz it is a 15 AMP battery and I usually use a cheap 12 AMP lawn mower battery. Any way the battery is more than 10 lb less and boy does it spin the starter.

If so, have you verified how long the lithium can keep it running if you lose the alternator? I ask, because many of the lithium starting batteries have tons of starting power, but very limited total energy. There's a big discussion among bigger homebuilt guys right now about how to determine total capacity. Bob Nuckolls recently wrote a good article about the issue in Kitplanes.
