FS91 II w/pump question.
I have a U-Can-Do-3D w/Saito 100 & am having a feed problem. It floods, I guess because of the tank to carb height it is gravity feeding. My question is, If I were to replace the Saito with the FS91/pump will the pump act as a regulator as well? I know there are add on regulators out there, just looking at other options.

By flooding I mean it is filling the intake to the point of overflow & hydro-lock when the engine is not running. I'm hoping maybe the FS91 pump will prevent this. Thanks for the help

BThomas,
With the O.S. Max FS-91 Surpass II w/pump, you would still get some siphoning if the fuel tank's too high in relation to the carburetor. This would most likely be the case in your existing setup. Usually, the pumped engine is used to allow for placement of the fuel tank farther away from the engine to eliminated changes in the model's balance as fuel is used.
