Mercury EFI 150 175 200 HP Fuel Vapor Separator 8140111 14817A31
This came off of a 1999 year model 200 hp mercury.
The electronic fuel pump is good in this VST.
I have not pulled the VST apart to inspect.
You can hear the float moving up and down freely.
I do not believe it is corroded.
This is missing a check valve. The last picture is a reference of what the exact valve looks like.
Selling as is.
