I notice on the B-17 I bought off a fellow last year, that he does not have mufflers on the pipes off the 26's. Which also means there is no line from the exhaust to the tank. The engiens run fine this way on the ground. Never flew it yet.

So now I am setting up another plane with this same engine. I have a combat P-51 from GP and have a new OS26 for it. I am wondering this, should I put the ehaust line on this plane? Can I go without it? I would rather go without if possible for cowl cutting reasons. Would be nice to have just the little pipe stuck through. Also, when putting the filler line in (using a Tee) the fuel line, will it flood my engine if the throttle is opened while fueling? Someone asked me this and I was unsuure, but thought it was a good question. So I asked you guy's.... Any advise appreciated.
