I'm going to run a new gas line on my '61. It has a 5/16 right now and I'm going to replace with 3/8 line and want to run it through the drive shaft tunnel.

I wallered under the car to check out the holes and I see two holes on the passenger side of the tunnel. Two holes on the back and two holes on the front. The e-brake cable is running through the bottom holes so that leaves the top hole for the gas line.

The hole looks somewhat small for a grommet and 3/8 line. Does the hole have to be enlarged any and if not, is there a specific size or "special" grommet that must be used? Or to I buy a grommet assortment and keep trying until I get the right size?

I had the thought of slipping a piece of hose over the line and let it be a wanna-be grommet...

I have the steel gas lines I got from Paul. Thanks Paul! And Paul mercifully labeled the sections for me and saved me at least two days trying to figure out which one goes where

So the middle section of gas line is the first one I'm going to put in then I will work on the rear section when I swap the tank. Then I'll see about fighting with the front section...

there are specific grommets sold for the 3/8 gas line that slide onto the gas line.The factory holes in the frame are not changed they fit the gas line with the grommets.
When installing the line with the grommets they can get pushed out of the frame by the gas line (hold them in place -use glass cleaner to make the gas line slide easier in the grommets).

If you need pictures of the gas line and grommets I can post some.

here is the part number for description from Show Cars

Part # 1083 -- 58-64 Gas line frame grommets, 2 piece set... Set - $4.79

I could not get the link to work for this part number.

Hi Paul,
I guess it would be you when I saw a reply. Thank you again for all the help and advice with this project. I still have the pictures you sent last year or more I'm pretty sure. If I can't find them I will give you a shout. I'm off to contact Show Cars now and order the grommets. They looked substantial in their picture. Going to order a spare set too!
thanks again...Dennis

I recently had to replace the bushings on my Corvair stabilizer shaft, and it has two 90 degree bends that the bushings had to go past. I put some silicone oil on the inside of the bushings, and they went past those turn without any problems. I highly recommend silicone oil whenever you need to install any bushing that have a tendency to be problematic. My bottle came with a Cannon copier many years ago, however, it is still available on eBay. A little pricey, but a bottle will last you a few lifetimes, so you can share it with your friends.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

GM may still sell a silicone lubricant, used in the window slides for tight glass. It has a small brush on the end.
