Hi my digital fuel gage is not working on my Yamaha prov 100 it is a 1997 model. The gage has a clear pipe that goes up to a small black box 2cm by 2cm by 1 cm. The pipe is empty. from the box it then goes up and connects to the gage. Should it be full? If so do I need to disconnect the pipe and let the air out or prime it some how. At present the gage just reads empty. <br /><br />Thanks<br /><br />DGPW<br /> if you can help please reply here or mail me at<br /> david.g.williams@intel.com
