Fender funny you bring this up. I'm working on my FB F15 now and I've been doing a lot of research on this. A good friend and respected builder told me that he used one large air tank per main with a valve mounted right at the main. Then from there to the sequencer. He said it works perfect. He uses two other tanks for the other gear, doors, and brakes. I've talked to some other people about it and they say it's not necessary but if it works it works. I think I'm going to give it a try on this jet. He's using electronic valves but nothing hi flow and 3 mm line. If anybody else can ring in and give your opinion, I'm all ears. Thanks Scott
