Does any one have a pic or diagram on the best way to run gas line from carb to gas tank so it does not sit right next to the exhaust?

thanks, J

The old picture/diagram often shown here with the gas line diagonally under the exhaust applied back when good exhaust pipes made by Ford were available. Most currently available repros hasn't got the right shape so there isn't enough space to route the line like in the picture without going too near the hot exhaust. Therefore I ran the pipe close to the hogshead instead.

Here's Ford's recommended route, check if it's possible on your car..

I didn't care for this. Too near the exhaust pipe.



So I did as Roger suggested.


It's not obvious from the pictures, but all of it is two inches or more from the pipe, and nowhere is it over the pipe to catch the rising heat.




Somebody suggested that I shouldn't have it fastened to the hogshead.

After a vapor lock problem I made sure the gas line went across the exhaust pipe at a right angle so it had the shortest exposure to the heat.
It crossed as high as possible and then went along the top of the frame.

I was not concerned if it was slightly up hill from the shutoff on the bottom of the tank as long as it stayed below the bottom of the tank, but I did try to keep it close to level.

Forgot to mention I also wrapped the exhaust pipe with header wrap from Autozone, and the gas line crossed the exhaust pipe back near the tank.

I think the only problem you might have is that the line is fixed to the hogshead. If you could make it more flexible or float it in a piece of rubber tubing you should never have a problem.

Not to be argumentative, but I don't see any problem with attaching the line to the hogshead. The engine is attached securely to the frame, as is the gas tank. If the engine were mounted in rubber so it could move with respect to the frame, it would be different.

Here are some pics of the original routing. The line is never closer than a couple of inches to the exhaust pipe. The pipe is a repro made by Vern Campbell, and it has couple more bends in it than the cheapos some of the vendors carry.

I have routed mine straight across from the fuel bulb to the frame above the exhaust pipe. Then down to a clamp at the cross shaft. Then along the lower frame rail and between the engine mount block and the frame to the carburetor. I haven't had any trouble with vapor lock. See pictures.
