1964 fuel filter - correct color

[Curt C.]

I looked in the archives concerning fuel filter GF-90 and whether the correct color is silver with red lettering or black with white lettering. There is much discussion but no conclusion. Are both correct and who makes the best reproduction? Thanks.

Re: 1964 fuel filter - correct color

Having just had my car Regionally judged either one is acceptable. Saw one 5 Star Bowtie car with Silver/Red. Sharp. As for a reproduction. Reference ebay under Corvette fuel filters. The seller is selling them for under $40 either color. He spent nearly two years researching these filters before producing them to original specs. You will not be disappointed. I am in no way associated with said seller to be clear.

Good luck,
Craig

I have included apicture for you to reference his work.

i have the original filter off the Grady Davis/Don Blatchley ZO6 and its silver with red print. the repo from corv spec of Md is very very close to the originals--it takes a mic to differentiate --its clearly the next best thing to an original. mike

The cannister looks pretty close.
What about the length of the Hex connection?

I've seen the repop on eBay. It appears to me that the taper on the end of the canister (inlet side) is too pronounced. The ginny I have has no taper at all.

got out the repo and the original, and by golly, ole TC pciked up on something i missed. the concavity( where the inlet fitting is attache3d to the main body of the filter) is significantly deeper on the repo than oln the original. also, the solder on the original seems to be more abundant than that of the repo. mike

Well folks then use an original. If it's not available then use a repo. It's that simple.

Re: 1964 fuel filter - correct color

Doc Mike is correct I also have a original and purchased Maryland's repo. there is a difference. Once a repro always a repro. it will never pass as a orignal and should be deducted for.

Mike, were you possibly a judge at the Regional Meet Chattannoga last month?

Re: 1964 fuel filter - correct color

Hello; I happen to collect GF-90's and have been doing so for 20 years or so. I sent 3 originals to Brain to use as samples in reproducing the ones he did. All 3 had NO notches on them. I have 6 Originals in my collection. Three of them are still on untouched 63 FI units. It appears to me that the 62's and some early 63's used the silver Gf-90s with the red print on them, then the black Gf-90s came out with the white print on them. I have also noticed 2 fonts on the filters, but they are so close it's hard to spot it. I have never seen an NOS no notch GF-90 and probably never will. I think that Brian did a fine job with his reproductions and that we have crossed the line in judging these wonderful corvettes. Next they will want to test the air in the tires to see if it is 1963 air? On a 64 I would use a Black GF-90 filter. PS: If anyone thinks that there was only ONE set of dies or fonts used in the production of Original filters you are wrong!

Andy, you are..... absolutely correct. There WERE two different fuel filters used during the 63 model year. In fact, the assembly line part number changed some time in, I believe, late December 62.

One filter was the silver with red print and the other was the black with white.
I have GM paperwork on the change. It was about the same time many of the zincad items were replaced with chrome items. (fuel filter bracket, oil filler tube, fuel lines etc etc.)
The reason for change was "to improve appearance".

Re: 1964 fuel filter - correct color

On my '64 I have a new repro black w/white letters......I don't have an AIM or Nolands in front of me, but I believe that's also what I remember those, or something calling out.

Could it be both? In other words Black w/white on certain motors and Silver w/Red on others?

So, assuming the last couple previous inputs above are correct as well, and Craig had his judged as well as he saw one 5 Star Bowtie car with Silver/Red and was OK, how does this finally get settled?

What judges/cars do we need to get together to arm wrestle this thing into submission......

The only way I can think of to sort out the part numbers is to find out what the number is that's listed in the 62 AIM and see if it's the same as that shown in the 64 AIM. (I don't think it will be)
We know the filter on 62 FI cars was always silver?

I know the part number and color changed for the 63 model some time around late Dec 62 but I don't remember for sure which way it changed. I THINK it was changed from silver with red characters to black with white characters.

The original assy line filter from start of production of the 63 model was a 5650612. That was changed to a 5650703 in late January 62.
Pretty sure the 612 is silver with red printing and the 703 is black with white printing.
