I’ve received a rolling chassis and noticed the fuel pipe runs through the tunnel but is not supported by anything - is this normal or should I fix it to something to prevent it wobbling about?

I opened my tunnel up to work on a new choke cable I was installing (which is another story unto itself) and noticed that my gas line was secured with several nylon tie straps on a metal brace that went sideways across the tunnel, where the choke cable pipe was "tack welded" onto the brace. There may have been some additional nylon wraps toward the front of the car holding it down but since I didn't need to go down that far I can't say if there were more down there or not.....
It would be interesting to learn more about your choke cable project.
I thought about using the lever on the left side of the parking brake for choke cables. It is not doing anything now. Of course, the thing I removed on the side of my Weber carbs is not really a choke.
Michael....I believe the choke on these Webers is not a typical "butterfly"in the air horn of the carbs. It's an enriching valve built into the carb that is activated by the manual choke cable. My old Fiat Abarth had this system and it worked well. Only for warm up though. .It didn't have an "unloader" spring like our common "butterfly valve" choke does. If you tried to take off with the Weber choke still on, the car would choke and belch black smoke and nearly not run at all...........Bruce
I had the Weber "chokes" hooked up on my car early on back around 2005-6. They richen the mixture a LOT. It's not needed for long, that's for sure.
The thing is, there are TWO of the "enrichment valves", so I made a splitter to go from one cable to two. It worked really well, but I figured out that I really didn't need it.*NOTE: this is part of the infamous "Lane Anderson brass thingy" parts.
Not long after, I changed it to just a hand throttle. That's really all I needed. Come to think of it, I might put it back in, probably easier than cold-start EFI tuning...
I used bicycle shifter cable and housing for all of it. I used a thumb shifter for the lever.
Back to the gas line in the tunnel. Mine is a VS, it had a type of clean silicon probably 2" thick gooped up on it as it came out of the tunnel. Worked good until I had a gas leak where it meets the gas line hose. Started to erode it, so I need to scrape it off and replace it.
I never liked that "wad" of silicon either. I guess it works but there has to be a better way. I'm surprised that gasoline eroded it. Perhaps it is a building contractor's silicone that isn't impervious to gasoline. I good HD neoprene grommet would look better and maybe work better too.............Bruce
There is a rubber VW part for each end where the line enters and exits.
