Black Fuel Filter Bracket On 63 L75

[Michael H.]

Has anyone ever seen a semi gloss black painted fuel filter bracket on a 63 L75 300 HP?

Re: Black Fuel Filter Bracket On 63 L75

Michael, I have seen zincad ones and chrome but no black. Maybe a pilot car could have had black since they painted a number of parts black on those. I guess it was a quick way to bolt the car together for testing rather than waste time with the platers. But no I never heard of a black one. Why don't you put a nice pic of one on the board. I know you like what is not typical and that's what makes your posts so interesting. RJ on the other hand likes typical. Jr.

JD Black filter bracket is rarer than Greensberg PA banana trees blooming in winter.Tell Michael what markings are on filter brackets in 63.RJ

Re: Black Fuel Filter Bracket On 63 L75

Rj, I am sure that you know that the '63 fuel filter bracket is different that the 64-65. What's the difference Sr. By the way the marking on an "original" I just looked at says PR. My little white car has a NOS ugly chrome one on it but it isn't correct. Yes It's NOS and yes the nickel type chrome looks like it was plated in a bath tub but the configuration is not correct for 63 but it fits. Very few people know that '63 was on its own. So go ahead Sr. let's see how smart you are. Jr.

3rd Edition JG Disagrees

Thanks John. The 3rd edition of the JG, page 103, section 9, Fuel Delivery System, states that "1963 L75 fuel filter brackets are painted semi gloss black". I've never seen one painted semi gloss black and just wondered if any one else has. I know that pilot line car #2 had a zincad bracket.

In the same paragraph, it also states that the fuel filter bracket is "secured to the stud with a hex nut and star washer". I believe this may be in error also.

Re: 3rd Edition JG Disagrees

Mikey, My knowledge is limited to the fuel injection filter brackets. I know that they were cad-zinc on the early models and then they were a cross between nickel and chrome on the later models. Talking about 63. I am not familiar with the L75 bracket as to whether or not it is painted or what. SOmeone who knows this had better jump in and help. John

Re: 3rd Edition JG Disagrees

The 4th edition says: "1963 L75 brackets are painted semi-gloss black. 1964 L75 brackets are cadmium or zinc plated. Both 1963 and 1964 L76 and L84 brackets are chrome plated. Very early 1963 L76 and L84 brackets are cadmium or zinc plated."

Re: 3rd Edition JG Disagrees

AIM L-75/L-76 Section (sheet 3.00) calls out 3825914 for L-75, 3834122 for L-76; no indication that these part numbers or screw part number changed from first release so likely all regular production should be the same regardless of production time frame.

L-84 section (Sheet 5.00) says: "Part numbers and installation same as RPO L75-76", which implies either is acceptable, but I believe it's generally accepted that L-84 used the same chrome plated part as L-76.

Since the only difference is cosmetic, engineering would have readily approved sustituting one for the other is one of the part numbers was exhausted from production stock.

Re: 3rd Edition JG Disagrees

Duke,

Pretty sure the difference between the two part numbers was the plating. In fact I'm 100% sure. All engines (except 250 HP) used a zincad bracket until probably some time in December 62. At that time, the L76 and L84 received a chrome bracket. The L75 300 HP continued using the 3825914 zincad bracket through the end of production. The L76 and L84 continued using the 3834122 through the end of 63 production.

I've never seen a black painted filter bracket on any 63 engine and would suggest that the JG be corrected to show this. Does any one agree/disagree/

Re: 3rd Edition JG Disagrees

Michael,

agree 100% - and, BTW, the 2nd edition has the same error

[Robert Jorjorian]

Re: 3rd Edition JG Disagrees

I agree NO BLACK filter bracket.

I also feel that Michael's second paragraph quoting the JG's definition attaching hardware has an error also.

There should be a thin (jam) nut and FLAT washer, NOT a star washer that the JG calls for, holding the filter bracket to the stud.
Merry Christmas, Robert

10-4 on the thing jam nut.

Don't know about the washer but that doesn't sound like a normal application for a star washer.

Re: 10-4 on the thing jam nut.

Of two different L-75's in Noland's book, one is black and one is either zinc or chrome; there are three more in the Dobbins book, and all are either zinc or chrome.

Re: 10-4 on the thing jam nut.

Thanks John. Does the car with the L75 and black filter bracket appear to be original or a restoration? If it's a factory photo, it will be the first I've ever seen with a black bracket.

[John H.]

Re: 10-4 on the thing jam nut.

Michael -

The one with the black bracket doesn't appear to be a factory photo, and the one with the zinc or chrome bracket does appear to be a factory photo.
