63 Fuel Line from Pump to Carburetor

Re: 63 Fuel Line from Pump to Carburetor

If the repro part was designed, made and sold by a Chinese company, I would agree. If the part is made in China, on behalf of and sold by a US company, like ZIP, Paragon, CC, CSofMW, etc., I would blame the US company for accepting and selling a poor/defective/inaccurate/etc repro part.

Re: 63 Fuel Line from Pump to Carburetor

Started engine and brought up to operating temp twice now and found the thread sealer to be working on the fittings connected to the filter. Got a little seepage from the threads on the lower connection of the filter-to-carb tube. This is a compression fitting so I'm thinking the flare on the tube is not seating correctly into the fitting. The tube does look a little out of alignment with the fitting. Or maybe the fitting needs to be replaced. I'll loosen the fittings up and try to straighten things out and re-tighten again.

Thanks for that. I was not aware.

Re: 63 Fuel Line from Pump to Carburetor

I really like the rare original adapter stud with the indented circle. I used to hear in the old days that the screws holding the clamp tight should have a blunt end. Not pointy.

I have the correct thin washer in my catalog. No one ever buys one.
Free part: The first hundred that want a washer I will mail you one for free. Just email your address. johndegreg@aol.com
P.S. Must be a paid up member of NCRS for free washer.

I am including a couple more pictures of the stud end as an additional reference.
I now know I am missing the correct star washer.

Pictured is what Zip sells as correct for the fuel filter retaining stud.
They include a flat washer not the star washer.
Certainly it has no "C" on the end of the stud.

Re: 63 Fuel Line from Pump to Carburetor

I'm getting fuel leakage again through the threads of the fittings connecting to the front and rear of the fuel filter. The thread sealer I applied worked for a couple of weeks but fuel is getting through again. I have re-tightened as far as possible but still leaks. I believe the problem is that two the fittings have a slight tapered profile so that they will seal as the filter is tightened down. It seems that the threaded connections on the new filter allow the fittings to screw all the way into the filter connection so there is no way the threads can seal properly. This was not the case on my original filter which did not leak at all and had no thread sealer. I believe that after the filter is installed there should still be some threads visible on the two fittings. This would ensure proper thread seal.

Any suggestions?

Re: 63 Fuel Line from Pump to Carburetor

I fought this same battle and finally won.
I believe it's just badly manufactured parts.
I even went through the trouble to purchase extra chrome lines in case I had to take it apart again.
They manufacture small copper washers for flairs on the brake lines. I have never used them but when all else flails?
The issue is I don't know where to get them or even if they are available for 5/16 lines.
Since yours sealed with the old lines I suspect it's the filter. I would possible purchase another and cross my fingers they weren't made at the same manufacture. I have a pile of parts that didn't function or were advertised as period replacements that weren't.
That last purchase was a distributor cap. Called out as a replacement in judging. Still attempting to figure out the differences.
Will save that for another posting.

Re: 63 Fuel Line from Pump to Carburetor

Fortunately I save my old filter because I re-installed it and now have no leaks at the front and rear filter fittings and didn't have to use and thread sealer. The old filter is apparently a replacement from which I'm told is not 100% correct for judging purposes due to notches in the fittings and the wrong style "9". But this new "correct" filter I purchased is not a good fit not only because the threads won't seal but also because the chrome elbow fittings were able to screw so far into the filter that the fuel line from the filter to the fuel pump was almost touching the cylinder head again. Now there is good clearance there.

At this point I don't know whether to buy new elbow fittings which will work with this new filter and who sells the correct ones. The ones I have may be original but I don't know how to determine that. All I know is that they work with and older replacement filter.

Re: 63 Fuel Line from Pump to Carburetor

The fuel line from the fuel pump to the fuel filter on my 63 - 340hp is in contact with the front of the engine block which is probably not a good thing. The "Fuel line from Fuel pump to Carb kits" I see online show a fourth fitting which I don't have. This would be a straight fitting which would mount to the front or rear of the fuel filter. This would move the fuel line to the pump away from the front of the engine block. I've seen several cars without this fitting and my copy of the AIM doesn't show it. Anyone have this fitting and know which side of the filter would be the correct location for it? Thanks

The Original filter G-F90 didn't have the notch's on each end , this is on my 63thumbnail.jpgz06 1120.jpg
