Default Bubbleless with pumped engines.

I was wondering if any of you have experience with bubbleless tanks and pumped engines? I have a patriot with a OS VF 46. I put a bubbless tank in it last year and its the single biggest improvement i have ever experience with a glow engine. I recently purchaced another patriot in box and will be putting a YS 45 RE in this one. The other patriot is 16ys old and still smokin but my YS is bored. One can never have too many patriots
Would I get the same benifit with the YS as the OS?

Thanks,
Cody

I believe the pump eliminates the need for a bubbless tank. Not sure how well it would work with thw YS as it pressurizes the tank and then regulates the feed through the pump. I would say go with the venting that YS reommends.

no.....

because on a bubble free system you can not return the fuel to the tank. It is pressurized on the outside of the bladder.

The YS pressure side is also the fuel return.

Just make sure the fuel system is tight and the YS will run fine with just about any regular fuel tank.
