Topic: NOS C7ZZ-3494-A 1967 Mustang Power Steering Hose

C7ZZ-3494-A (engineering number stamped C7ZA-3494-B)

This is a one year only power steering hose that connects to the pump high-pressure hose at the insulator and then routes down to the valve body.

The Ford MPC indicates this hose was used up to June 19, 1967 production but actual changeover date on the production line varied due to production line stock. If your car's production date is close to this change over date you should check your control valve port size. If your car was built after 6-19-67 you will need the larger port C7ZZ-3494-B hose. (This information was attained from Dead Nuts On Concourse Restoration Website)

This hose has the smaller 7/16 inch wrench size control valve fitting for the early control valve, not the 1/2 inch wrench size control valve fitting used on the later cars with the larger valve.
This hose has the small FoMoCo logo die stamped next to the engineering number, reproductions don?t. From my research, this hose is correct for early 67 HiPo 289 and 390 and early all GT350/GT500 cars with the smaller control valve.

Believe the early hose has a 1/4" control valve fitting.  The later hose has a 5/16" control valve fitting.

It's a 7/16" wrench size versus a 1/2" wrench size. He has the early one.


Not sure if a GT-350 would use the big block PS pressure hose. My guess would be no.
