Looking for some suggestions on how to fuel a YS 120 in cowl. I really like using the Du-Bro fueling valves, but I've never dealt with a YS engine before. Do I use a 3 line tank, or do I put a tee in the line with the check valve or ? I would appreciate any suggestions.

Thanks

The YS 4 strokes are all pumped so you don't need to use a 3rd line, although you can if you wish. The check valve goes on the pressure line so no fuel should run through it, but you do need a place for the air to go when fueling. A T between the tank and the check valve, going to a fuel dot or other closable fueler is good. When fueling you open this line to let the air out. The T in the fuel line should be between the tank and filter and must be closable also with either fueler valve or fuel dot. The system must be closable as pressure is developed in the tank by the engine.

I used two "T's" and two fuel dots. You just have to remember to burp the YS vent line so fuel doesn't squirt out when you pull the fuel line. With the higher fuel tank pressure, I wouldnt use any type of a fueling valve.
