Default Re: Filling holes in firewall.

Nothing but a fuel valve, fuel line, and a sediment bowl attachment just above the heater carry through inside the cab if so equipped. The sediment bowl, carb feed line, and carburetor are on the engine side in that right side area. It just depends on where the unwanted holes are. If the holes are on the left side then there is less chance of problems. Welding stuff up throws a lot of sparks and they go everywhere if using MIG. I gas weld myself but that little torch puts out a pretty good sized flame. I wouldn't want all that fuel system stuff even close to where I'd be welding. After the welding then the grinding begins and that will throw sparks everywhere.

A lot of these old cars have had aftermarket heater set ups installed and some of them end up with a lot of extra holes they don't need.
