You should be able to use any 324kpa/46psi/3bar submersible fuel pump even from a car. Check the link below near the bottom for in tank fuel pumps.

If you can't get a submersible pump to fit inside the fuel tank, get a outside inline fuel pump with the pressures above & fit it on the outside of the fuel tank. Keep the existing Yamaha connectors for the fuel rail & tank, cut the Yamaha pipe in half & fit some hi pressure fuel hose & fit the inline fuel pump in between. Remove the Yamaha fuel pump from the the tank so there is no restriction.

Any of these ones with 3 bars will do.

Actually, there's one available from Italy:

..worth a try, i guess.

Good luck,

Wow just read this one, how are you doing?? Did you get the bike running??? I guess that fuel injection is tricky in countries with poor quality fuel. Should you fit an extra fuel filter?? Should you be using STP to keep the injectors clean?? Are there other extra precautions that can be useful in cases like this??? Mind you I guess carbs also get clogged so I would vote for an extra filter prior to the fuel getting to the injectors. Good luck!!!

Jeez, bad luck bud. Of all the places to get stuck, Liberia would be hard enough on a fully operational bike.
Have you tried asking for help on

Hope I'm not breaking forum rules here. But there's loads of bikers on this who are world travellers.

Best of luck. Let us know how you get on.

Clean a fuel filter or injector

Undo the fuel filter and see if there are dirt in the fuel that comes out
Fuel seems to be the problem, if you checked all the other stuff

I do hope he's still not stuck after all this time guys!!!:thumbleweed:
