Ryobi 725R Weedeater Primer/Gas Line Replace ?

Hello,
I am trying to replace my primer switch and gas lines. On this weedeater it has two holes in the gas tank. The primer replacement bulb I bought has a hose to go into one hole of the gas tank and one hose to go into the carburator.

My two questions are:

1) Does anyone have a picture of this weedeater's tubes for me to go off of?

2) What/where does the 2nd hole in the gas tank connect too? Do I need to buy just another gas line or do I need some type of stopper/filter/ect to hold this line in?

Thank you

If you need to email me please email rwolhar@hotmail.com

Thank you!

 

It should have a line from the tank to the primer, one from the primer to the carb, and one with a filter in the tank going directly to feed the carburetor. There are normally little collars on the line - not sure about that model, though. The line may fit tight enough to hold it in place without the collar.
