Model T Ford Forum: Forum 2015: Holes in Firewall
Top of pagePrevious messageNext messageBottom of page Link to this message  By Forrest Kahle on Saturday, February 28, 2015 - 02:48 pm:

I have three 3/16 inch holes in my firewall that will be blocked when I have permanently installed the gas tank under the cowl of my 1926 Coupe. Does anyone know what they might have been for or if I need to put anything in them before I finalize the tank and instrument panel? Some old photos show a series of insulator stand-offs mounted on the firewall, but I certainly had no such attachments before I started restoring.
The attached photo shows the locations outlined with yellow tags.
I want to be certain I am safe before I go any further.Firewall Penetrations at yellow tags

There should be a fourth hole which would make a rectangle if you were to connect the holes with lines. There was originally two pieces of webbing attached vertically on the inside between the gas tank and the firewall. The heads of the rivets would be on the outside and the bent legs of the rivets on the inside, This would be attached similarly to the band material on the bands. There are also metal strips with rivet holes on the underside of the cowel for webbing to pad the top side of the tank from the cowel.

Just in support of the answers above, Norman is correct. There should be a fourth hole. The 4 holes were used in part of 1926. The three parts Ken linked to in the post above is what is required to mount a gas tank in a 1926. I believe the rivets for the four holes are the same rivets used to mount the hood lacing on the cowl.

You hit it on the head! Thank you so much!
I used self-adhesive webbing, so I didn't need the rivets. Now I know how to correct the problem.
Thanks for the compliment on the paint job. I had a team of us trying to match the antique "Channel Green" to a modern paint formula. She does look kinda pretty, huh?Paint Shop Delivery of My Baby

Too bad you let the state rivet that ID tag on your firewall. I'd never let them do that.
