One tank or two, Sir?

Also loved the Redbay Cabin Rib with twin Suzi 200s, but only single fuel tank which surprised me,but the cockpit & cabin looked very impressive. I'm sure there was lots else, but had limited time and for some reason had difficulty getting away from the Ribcraft Stand.

But did you ask them how big the tank was 🤑

400l giving range of c. 250 NM I thin.

Just surprised 2 engines drawing off a single tank. I'd have thought separate tanks to minimise risk of contamination etc.. would be the ideal.

If you're going twin tanks with that in mind, you would need seperate batteries filters & fill the tanks at different pumps. Then valves and switches to mix & match engines batteries tanks & filters

Exactly 👍 it's been done to death has this subject over the years.
Mine draw off one tank with separate filters never had an issue
Don't think I could be bothered going to different fuel stations to fill up.

That doesn't take into consideration a split tank/hose etc etc. I've had two issues with fuel, first time I was stupidly running off a single tank and ruined 12 injectors, had to get a tow in. Second time running off twin tanks one engine went down, was able to run home at 25knts and 'only' had to replace 6 injectors. In both cases it was an issue with water getting into a tank rather than a bad fill.

If your doing proper offshore stuff or operating in remote locations it's well worth the effort.

No fuel filter/glass bowl with drain screw to separate water?

Cheaper than a load of injectors.

I thought most engines from this century had a small internal filter for water anyway and once full engine goes to limp mode... to save stuff getting damaged.

I may be wrong.

We had water in system once, went in to limp mode. So we took cowl off, drained internal filter, then drained glass bowl. Engine then ran fine and in the 30min run home we stopped to drain the glass bowl once when we saw it fill up. Then drained the tank once back home.

Most twin engines have totally separate batteries and charging systems & filters often the only shared component is the fuel tank
