cat convertor
 

Purchased Benchmark Cat. Has a tube with a fitting running up passanger side, what is this for?
928 1983 man trans:confused:

Air pump tube?? Do you still have the air pump mounted?

Have an air pump
So a tube runs to it?
Idea were to find one?

What State do you live in? The only ones that are legal are 49 state ones. It is made by Walker. The Tube goes to a Diverter Valve which then goes to the Air Pump. If your in California, your outta luck as they are illegal.

Here's a screaming deal

Wow, scoop this up.

I should have waited to replace mine on my '84. Bought mine in very nice USED condition from 928 International about a year ago for close to that price. :rolleyes:
