Get the number off the carb. probably Zama? go to Zamacarb.com should show you diagram of your fuel system. If not goggle how do I change the Fuel lines on my mantis tiller should come up with something?

Go to mantis site sent an email and ask Mantis people. Or call the number, let them tell you what engine and model you have and let them point you to the right manual. They have manuals for all the models, problem is they change to 4 or 5 different engines through out the years and you cannot take for granted.

Thanks for all the help. After googling for information these past years, it never occured to me there could be a human out there to call. But, I did and all is well.

Still having some priming trouble but am confident all lines are in place. Will certainly resolve that soon.
Thanks
