Topic: 69 Boss 302 Power Steering

[hopey]

Here are pictures of the 69 B2 Pump end pressure.
Part number C9ZA 3A719 D,  yes D.

Dan,

That is an engineering number, not the Ford part number.

What is the part number for this particular hose with this type fitting?

What is the part number for this particular hose with this type fitting?

From a late 69 MPC. As a reminder for others the oil cooler *listed below the wo/oil cooler group shown below, was not an option nor available from the factory on production 69 Boss 302's, so can't explain why Ford would list it other than just an error/miscommunication. Since Ford was always consolidating parts to reduce the need for additional inventory we can't be certain that the part numbers shown are the exact ones that were installed on the line, even only a couple of months after production had ended.  Guess another place to look is the Assembly Manual reprints but don't know if they list the application


Sorry don't have a MPS printed between May and Aug 69

Dan,

That is a part number indeed - you can call it an "engineering part number", or "casting part number" but it is still a "number" on a "part".  I've seen some Ford documents also refer to parts using the very generic "item number" terminology.

What it is not is the "service part number".  The Ford "Parts and Accessories Catalog" (with varying names including, depending on the specific publication, the "Master Parts and Accessories Catalog" (see the attached and often abbreviated as the MPC) lists the service part numbers.

Sometimes the item number (engineering number, casting number, etc.) is one and the same as the service part number.

So that is saying a cooler was not a option???  This B2 has a cooler and hoses are certainly original.
Did Ford dealer install these?  If dealer installed can it be considered original?

Someone else that understands.

Thanks Jim.  I guess I should since I designed a few Ford parts that are in the books. 

Quiz: When it a service part number technically not for a part?

Answer: When it represents a kit (that is comprised of multiple individually serviced parts...and occasionally with some of those serviced parts that are assembled from several individual engineered parts, each of which have part numbers...)

I believe the MPC is referring to with and without "POWER STEERING OIL COOLER".  In the text for the 69F 302 "with oil cooler" the MPC includes line item part numbers for the bulk return hose and insulation used with the power steering oil cooler. The text for 69F 302 W/O oil cooler does not include those items.  My extra NOS 1969 Boss 302 Power steering Pressure Hose is Tagged C9ZZ 3A719-C...... the engineering number stamped on the fitting is difficult to read (chokostang shows a photo of the eng # as-D).  The length of this hose is definitely NOT 27 inches as the C9ZZ 3A719-A (69F 302 W/O Oil Cooler).  If anyone would like detailed photos or measurements of installed system or loose NOS hose I can supply..... To my knowledge the C9ZZ-C hose has not been reproduced and is very difficult to find NOS or used!

Some of my "Ford" designs are in space, as in Ford Aerospace & Communications Corp.

Were 69 Boss 302's with PS built without the oil coolers for PS ?  If so, when and if we know, why?

[chockostang]

Yes, I have heard both versions,  I never got this cleared up in my head for 20 years.  See cars with BF pumps,  "Owner says-That is totally original",  69's with Bottom radiator hose on Drivers side, steel cradle- "Owner===That is totally original-late 69".
I'm very convinced the PS option was a option on 69 using the C7AA Aluminum bracket, the steel support with no hole, the C9ZA 3A719 D numbered pump end pressure, the lower hoses same as 351W.Pump a HBA BK (Return turn 90 degrees straight down, and with a cooler.
Sure do appreciate all that chimed in here.  Kerry Mcmann and I can discuss the situation.

I am attempting to find a replacement for the power steering pressure hose for my 1969 BOSS 302, what I believe to be C9ZZ 3A719-C.  I also understand form the forum that this part is extremely hard to find and is not to my knowledge being reproduced.  Assuming NOS or used original cannot be located, what would you suggest as the most suitable alternative?

Given the site and our focus I don't believe there is a suitable alternative. Would guess that your going to have to find or make something that will make the power steering work while you wait and search for something better

Going to add your post and thread to the other related thread on the same subject

Often times, Boss 302 engines would have a designation of "Special", to differentiate them from the common F code 302-2V engines. (same as K code 289)
The G code Boss 302 engine, was introduced mid year 1969, we might not always find it in some versions of the MPC. I looked up the those hoses in my Mercury MPC. No listing for the Boss2 engine specific engine either. Posting findings from 1969 and 1970.
