I have been asked by customers what the difference is between a 69 and 70-71 headlight washer check valve. So while I have a few of each I figured I would post a picture of a 69 headlight washer check valve next to a 70-71. The 69 valve is on the left and the only difference is the center port. It is 3/16" while the 2 side ports are 1/8". The 70-71 valve has all 3 ports 1/8".
The position they are placed also differs from 69 to 70-71. The 69's used one at the front of the car just as the washer hose split to go to each headlight assembly. 69's also used one at the wiper motor/pump. 70-71 used 2 at each headlight where the hose split off to each squirter
As a side note I have also included a picture of the 69 washer hose TEE's that are used where the hose splits on each headlight to go to the squirters. These smaller TEE's are unique to the Corvette and Camaro in 69. In the picture of the 69 TEE's I included a normal 1/8 x 1/8 x 1/8 TEE for comparison.
The last picture is of the unique 69 washer pump Y connector. The center port is 3/16" while the 2 outer ports are 1/8" None of these TEE's, Y's or valves are being made in the correct configuration that I know of.
Question, Comments or Corretions are welcome. Untill a year or 2 ago I thought all the check valves were the same till I really started digging into this.
