Restoring a 69Z built in Norwood . Looking at the original rubber fuel line ink stamp it reads GM SQUARE BOX GAS . Does anyone have that stamp?thanks
-
I think Lloyd made some and they looked great.
I had a friend proto-type a 3D printed plastic "Stamp" and I have attempted to transfer (paint) to NAPA 3/8" fuel line scrubbed of the inked stamps. It 'Kinda' worked, still a "work in progress" for me. I plan on sourcing a proper in line Rubber style stamp and obtain appropriate INK designed to apply to and handle the rigors of fuel lines.

Jim, thanks for the kind words, and you're correct, I've had several ink stamps made for my current restoration project however as the original fuel hoses were not dry rotted and in overall good condition, I re-used them. To my knowledge none of the parts vendors offer a correct fuel hose stamp.

GAS [] GM GAS [] GM GAS [] etc,,,,,,,,,,,,,

Yes, that’s the repeat. Likely originally applied with a machine roller ink stamp.

& two different Fonts for the GAS -vs- GM.
Thanks

This a different design. This is from Guy's 12k L78 69. Gm used thousands of feet of these hoses & many manfactures would've been used....Joe

Here's a source for specialty inks that work on rubber hoses:
I still have bottles of AEROBRAND #1332 ink in white, yellow, red, and silver pigments/colors from the Specialty Ink Company that I purchased over a decade ago...but not much left. I used these inks to custom stamp various rubber hoses for my car and other people's cars. However. sometime since my original purchase over a decade ago, IIMAK Inks (Phone 800-685-6275 or 800-964-6275) out of Amherst, NY acquired Specialty Ink Company's business, including its formulas, brands, processes, etc. Attached are grayscale PDF copies of the latest IIMAK Inks catalog that I downloaded from the following vendor web site: https://www.americanmarking.com/uploads/IIMAK-Specialty-Inks-Product-Guide-Web.pdf. I had to break it into two documents (i.e., pages 1 - 3, and pages 4 - 7) and change it from color to grayscale and do some other creative things to get the document down to 500 KB or less in file size order to post it on CRG.
Looking at page 5 of their catalog in the AEROBRAND Specialty Inks section, it appears that Product #1141 could also work on rubber hoses. The catalog states it works on the following surfaces: "Non-Porous Tires, Rubber hoses." You may have to call for availability of any pigments not listed in the catalog.

Something I've been working on for my project, still a work in porgress.

Lloyd, I’d buy that.

Edgemont - you hit it right out of the ball park!!
When do you start selling it????

I had a stamp made to duplicate the fonts, point sizes, spacing and square symbol used on the original fuel hose I removed for my project. I mixed Liquitex white artists latex paint, which adheres to rubber well and is flexible, with some black to tone down the brightness and thinned it with water. Using an un-inked stamp pad I saturated the pad with the thinned, mixed paint and applied the stamp impression in a series following the original spacing. On factory original fuel lines, after several stamp impressions a date stamp was inserted however on short lengths like this, it was sometimes omitted (out of series) as was the case with my original fuel hose. I sourced gator style textured 3/8" ID fuel hose similar to the original. The rear fuel hose is 4 1/2" .

I did the Same thing, but am having imprint problems. Flat Stamp on a curved surface

Jim, you might try a couple of these tips for better results:
- Clean the hose with a cloth using Lacquer Thinner, a couple of wipes should do and it will make the rubber surface more receptive to the ink/paint. I remove any manufacturer's ink markings at the same time.
- Stretch the fuel hose and clamp it on both ends to a (flat) table using Irwin style clamps.
- Use a latex based ink / paint which is readily available at most craft stores and thin it about 20% with water.
- When applying the wet stamp to the fuel hose, to overcome the round shape, I "roll" the stamp front to back, holding the stamp block (rather than the handle) with both hands, for even pressure and good alignment.
Good luck!

Personally, I wouldn't worry about making them perfect as they were far from that as OEM.

Added the front fuel hose which is 10 1/2"

Great work and detail as always Lloyd and look forward to seeing this over the top restoration in 2024. Nothing wrong, just trying to understand the sequence on the hose at gas tank as it has two GM ink stamps side by side vs. the sequence of GM GAS , GM GAS? Matched something found in original hose?
Again, great work......

Chick, thanks for the feedback, doesn't surprise me for a second you caught the stamping anomaly - eagle eyes! During the stamping process I would need to wipe off (with a damp cloth) an impression that wasn't good, then re-apply (mis-aligned, smudged etc). Somehow I managed to partially wipe off a stamping (the word GAS only) only to continue with the full, repeating stamp resulting in omitting the word GAS from the series. I noticed this only after I installed the hose and photographed it. Thought is would be good enough to illustrate the work...but you caught it. I've since corrected in on the Z. Good catch Chick!
