'67 GT500 Air Filter Identification

I C U Tim

 

Originals have a larger diamond mesh but so do a lot of the earlier Motorcraft service replacements. They are all under the EDJ 9601 A part # but factory originals have FoMoCo silkscreened on the inside mesh. I think they also have the word "TOP" on the rubber.

so how did you know I'd reply to this post?

 

I saw you in here and I ran out

 

Is the filter paper white or yellow in color?

 

Since its used I doubt you can tell the color anymore. Originals are manila but so are the early Motorcraft replacements. I just looked at one I have and it has FoMoCo in script inside an oval and EDJ 9601 A silkscreened on the inside mesh. The word TOP is in silver and stamped on top black rubber. I looked at one of the early Motorcraft ones and it has no silkscreening and the EDJ 9601 A is stamped on the black rubber.

 

It sounds like you have one of the replacement filters made by the OEM mfg. The silver TOP should be accompanied by a silver AUTOLITE on a later Ford service filter. I have seen other Fram filters that didn't have the AUTOLITE but still had the TOP printed in silver. There is nothing wrong with that. If you are in the state of mind that it is killing you that your filter is not a assemblyline filter then by all means look for one and replace it . You will be the only one that knows it once replaced. None of the concours venues are going to take your air cleaner apart to verify the silk screen FOMOCO and in the non NOS/assemblyline part classes it is not a issue. The most important thing and the tip off is that it has the correct color paper,color rubber, and the correct wire mesh. Just my 2 cents. Bob

 

Out of the three different manila oval filts I have here, One is 1 3/4" tall and "motorcraft fa-48" in silver on top the black rubber. two is 1 3/4" tall and fomoco in an oval with part number EDJ-9601-A in ink stamped on the inside screening and "Top" in silver [1/4" x 3/4"] stamped on the black rubber, and the third is 2" tall and "top" in silver [1/2" x 1 1/4] stamped in the black rubber,its a little dirty to see any fomoco or part number. The question I have is, did the '67 gt500 and the 68 gt500 use the same filter or were they different hights?

 

67 and 68s used the same filter. The 2" tall version is the one used on the 427 4x2 cars I believe there is a C3 and a C5 version of those. Just to muddy the waters I have 5 different versions of the Motorcraft FA 48 (EDJ 9601 A) filters.

 

Thanks TLEA,... 5 variations,.. like one wasn't enough? Didn't the 427 filters have square screening and two different hights depending on what version of 427 was used?

 

I really don't know. I once had a 2" diamond screened version with FoMoCo and a C5 part # silkscreened and I looked it up. IIRC it was for a 65/66 Fairlane 427 4x2

 

Yes on on the square screening I have always thought the square screening was a very early variation. I also have had a 1 3/4 square screen as well. I have seen more of the diamond shaped screen 2 inch filters then the square ones (old stock used up?) I am not sure what was the criteria for the tall 427 filter and the shorter 427 . Hood clearance on the model line it was used on would be my first guess. I have always wondered about the application of the shorter then 1 3/4 filter . I don't have one handy to measure but it is shorter then the 1 3/4 one(probably 1 1/2). I have had it in grained in me for many years but I can't remember from where that it was used on the 68 GT350 . I have seen them on other 68 GT350's but the cars had enough miles on them that they would have been changed so they couldn't be used as a yardstick. Any thoughts? I almost forgot I have tried different solvents to spray through the filter to try and clean them and have had little success not good enough for show.

 

I've seen some shorter ones but thought the were replacement ones (1 5/8?) The 350s and 500s called the same part # for both.

 

Here's the filter on #1547. It's been on the car since the early 70's but good chance it was already replaced.

 

Open faced filters like this don't stay clean for long under normal driving. I had a new one on my 427 car that lasted about two years of weekend driving before it needed changing. [I keep a show filter in the trunk]

 

Shows how much us green horns know. I thought the orange rubber filters were the orig. ones.Thats what i put on the 67 500 i am finishing. I am not at my car right now but i think it is a autolite which i am sure is an early filter.

 

You listen well grasshopper. After you change the filter don't forget to take the Marti Autoworks tag off of the upper rad hose.
