Has anyone found a source for the assembly line Wittek Tower Clamps
used for Fuel Vapor Return Line Hose?

If anybody is still looking for these tower hose clamps, D&M Corvette in the Chicago area has some for sale. They say they got them from the closed Wittek warehouse. They are advertising them on a Facebook group.

I'm wrapping up a 69 RAIV. Can anyone confirm if the pump on the IV used that clamp?

The 69 GTO assembly manual shows all V8's using the mini tower hose clamps on the vapor return line at the fuel pump and frame connections. The pinch clamps are used back by the fuel tank.

You might give these folks a try, I saved this link off a long time ago, but I did buy some of these style clamps for my 66.

I wonder if these are used on the vapor return line on a 67 HO filter or 66 tri-power filter with vapor return down by frame? My guess is not, since the filter itself uses all pinch clamps.

The 67 assembly manual shows the second design fuel pump with the vapor return using these tower clamps, but I cannot find drawings for the HO filters to verify...
