Default Shocked at aftermarket parts

Hi folks,

In another thread, GT George mentioned that he had to replace his fuel pump. I had to replace mine in 2006. I'd like to tell my story here.

When my mechanic removed the old parts, both of us were shocked. I am the original owner of my car, so I knew that they were the original factory parts. The fuel pump was a Walbro, model #5520, mfd. 15988-1. The sender unit was part #E7ZF-9275-AA. The fuel filter was part #GF-510 (with "AC" in a circle). Does that mean it was a GM part? The rubber piece (seal?) was part #(upside-down triangle)E3EC-9B076-AA, MX13.

It appears that Ford put aftermarket (or third party) parts in my car at the factory. Why would Ford put Walbro and GM parts in my car? Could they have run out of parts? My car was built late in the model year (June 1988).

That's very interesting, the fuel pump I just replaced was the original to the car, it's a Ford part. My car is an 87 built 11/86.

That fuel filter number sure is an ACDelco number. It had to have been changed when you had the car serviced somewhere. My original fuel filter is long gone so I couldn't tell you what it was originally. The sender unit number you mentioned is a Ford number.

Because almost all the fuel pumps are made by Walbro. If Walbro puts a Ford part number on it, that's the way Ford wanted it. Ford may have run out of Ford marked pumps, so put Walbro marked ones in instead.

If the AC Delco part is less expensive, why would Ford care who made it? Many of the parts in your car were made in Japan, that's why they are Metric. Ford owned a large part of Mazda in 1988. Maybe you don't remember the Ford Probe fiasco? It almost became the Mustang.

Hi George,

To my knowledge, the fuel filter was never changed - unless it was done without my knowledge. But it is very unlikely.

In the early years of my car's existence, all of the servicing was done at Ford dealers - because it was still under warranty. Then, my car was taken off the road and put in storage in 1992. So, I don't know how an ACDelco part wound up on my car. If that part was added after my car left the factory, it was done by a Ford dealer.

Hi Blown,

Thanks for that piece of info. That goes a long way toward solving this mystery.

So, apparently, even the fuel pumps that are marked "Ford" were made by Walbro.

I see your point. But wouldn't Ford have "pride in their brand"? It just seems very strange to me that Ford would use an ACDelco/GM part at the factory. Ford is famous for sub-contracting out parts for their cars. They have been doing that for decades. It's a way of cutting costs. I get it. Using an aftermarket part is one thing, but using a major competitor's part is something entirely different.

Yes, I remember the Ford-Mazda relationship in the 1980s. And yes, I remember the "Probe scare" - where the Ford Probe was supposed to be the 4th generation Mustang.

I know when I changed out the original O2 Sensors they were marked with both the Ford Oval and Bosch.

If the Fords would have let Mr. Petersen do it his way & they wouldn't. '87-'88 were were big shakeup in management when Henry Ford II died in '87.

BTW, NIH (Not Invented here) is never a good policy & will eventually put a good company out of business.
