Sorry Gary, the trike is put away for the winter, otherwise I could answer that for you!  Man, things are moving right along!!   
Have you considered about 5 to 6 PSI of air pressure to pop that dent in the gas tank??  I wouldn't go any higher but that should be all the pressure you need.   
Right now I'm considering looking for a 1700cc Vmax motor for Goldie and a landing gear setup...
