How do I access the carb. to attach a new gas line from the tank on a Homelite Chainsaw 150 UT 10400A

I wish those posting answers could get things right.

The remote primer does not push fuel into the carburetor; it for pulling fuel mix through carburetor removing air line the system.

Here is the basic setup for a remote primer.

Unfortunately it's almost impossible to repair a leaking gas tank on a saw

throw the carb out and buy a new one. there is an internal issue that can not be fixed

I input your model number and found 3 possible matches, "42cc/46cc Chain Saw UT-10520; SUPER 2 Chain Saw UT-10520 or SUPER 2 Chain Saw UT-10520-A".
I opened the first "Ref # 3" on "Figure A" I suspect is what you say is leaking. It is very inexpensive and available. I would order one and inspect it once recieved to determine an installation method. It does not appear overly difficult without the part in hand. Good Luck.

The numbers Homelite & Ryobi use do not match the numbers everyone posts. A careful inspection of your saw should find something that matches.

If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck.

Thank You for using FixYa.

Off of the primer bulb there should be two lines, one goes to the tank, the other goes to the carb

No response to CR.

There is two sizes of line. I see the large one goes to the large port on the primer button and then to the fuel tank. The small one goes from the primer button to the carb. The problem is there are two hose connections on the carb. I believe one is a vent, but I am not sure what one it is. I have a 36cc 2-cycle model 358.352161

The line that hooks up at the front of the carb (#17 in picture) goes to the fuel tank. the line that hooks up at the rear of the carb (#18 in picture) goes to the primer bulb. Hope this all helps. Let me know. thanks.
