RE: which version OS 120 do i have?
Well I'm confused[].
I just got a used one that says.
FS- 120
Surpass On one side
OS
FS
Series on the other.
But it has a pump on the back? that says in,out,R on the pump. It looks like the "E" type if I look at the OS website. What model do I have?
Thanks
Shaun

"IN"--fuel from tank
"OUT"--to carburetor
"R"--return line to fuel tank.
The fuel tank will require one vent line that goes into the front-top of the tank and exits the aircraft at the bottom; one fuel pickup from the clunk inside the tank to the "IN" nipple on the pump; one line from the "R" nipple on the pump that goes into the front-bottom of the tank. The vent line is not attached to anything, but is left open to the atmosphere.

Thank you VERY much Bill..
I'm suprised this thing even ran. It was plummed as you stated. EXCEPT...........There are "T's" that connect the two of the lines together..
The (R)line, and the (out)line are connected by "T's . I have no idea why???[]
Thanks again for your help.
