You probably have to lengthen the hose. It may have split and somebody shortened it along the way. If you look at how it's run....it's supposed to drop down in front of that seal when you close the hood. If it's too short it will pull in and get pinched.
Is that a one way valve I see there, before the supply line hits the "T"? We just replaced the tubing on our 80 Volare and had to replace the T .....didnt know about that valve......
Guilty.
This is what came with my car. It definitely works, but is uniquely butt-ugly.
The folks who worked on it last didn't hook up the last line as you can see in this picture.
