Help with getting tuned pipe give pressure to a fuel tank

[pady]

Hello everyone, I just bought a plane that comes with a turned pipe. and i found out that the turned pipe has nothing to connect to the fuel tank. I am not sure what part should I get. after research, found this: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXCM34&P=OW

and I am not so sure that the right part I need to put on the tuned pipe to give prseeure to the fuel tank.

Since there have no hole to install the part, I would like to know if it is okay to drill a hole somewhere on the pipe and install the part? please tell me what part i need and how to install it.

Many Thanks

pressure fittings, drill and tap the pipe for the correct size fitting, brounelly law says the most pressure ocurrs at the fattest (biggest) section of the pipe, that ia where you should install the fitting.
Hope this helps

Thanks for reply. I am sure it will help.

Brounelly???
I believe the fellow's name is "Bernoulli".

brounelly

The result of a genetically engineered cross between Engineer Isambard Kingdom Brunel and the mathematician Daniel Bernoulli ? :D

But yes... put the tapping in the fat bit.

Not at all sure that Berbouili works in a TUNED pipe. IIRC the high pressure points are at the ends..one specifically to ram a charge of exhaust gas and raw fuel back into the cylinder. And the other because there have to be two to get resonance..

vintage, you are probably right, however.. as long as the pipe is at a higher pressure than atmospheric it ought to work fine, and perhaps going for the "fat" part of the pipe is less likely to spoil the tuning?

Science be damned. I've seen tuned pipes on the pattern planes of olde that had the tap at the fat junction between the two cones.

Go forth and plagarize my son..... :D

Well, if you look carefully, you will see I only commented on the applicability of old Bernie to the problem. I didn't offer any advice as to where to punch the silencer in the guts..since I know less than the square root of FA about setting up a tuned pipe engine :D
