Vert,

I used a Perry Pump on my 180 and the results were marginal. I ended up using an Iron Bay fuel regulator and I am VERY pleased with the results. The reason I needed the pump or the regulator was that my tank is above the needle valve with the engine mounted inverted.

I suggest you go with the Iron Bay regulator www.ironbaymodelcompany.com... It uses a pressurized the tank like the YS, all the parts you will need to complete installation is included. If you still want to use the pump let me know and I will make you a deal on mine... Probably less than 2 hours of use on it.
