Will a 9cc engine run properly without the provided fuel pump?? I read that installing a pressure line from the muffler works, on the ground is ok, after I installed a one way valve it seems to have too much pressure, some advise??

More info needed on engine eg make and on the installation.

Pics are good.

Your question can not be answered on what you have supplied so far.

ngh 9cc, apparently fuel pump;regulator not working properly, if I install fuel line fuel line from pump to carb will start and run actually it runs great, I'm afraid to fly it in that way, I believe it will need some pressure when flying, if I run a line from muffler does great, when I put a one way valve from muffler to tank, toooooo much pressure, so it floods, some advise??

You have two confiturations in which the engine runs "great" and you're looking for something else? I don't understand.
