I bought a perry pump V-30 for a Supertigre .75 because someone recommended it in order to save my warbird in case of an engine quit in midair.
I want to know if I should connect the muffler pressure tap to the tank as in any engine or if it is not necessary?
I read in another thread that I should install a tee fitting between the pump and the carburetor and send this extra tube line back into the tank. The instructions do not say anything about this.
Thanks for any Help.

I have a perry pump also. If its the same (and i think it is) blue can with hose. DO NOT run the muffler back pressure line back to the tank. either run it out the cowl, or just ommit it all together. the pump dose not need any pressure.

I dont see how a pump will save your plane once your engine has quit. I would only run a pump if I am haveing fuel draw problems.
