Fuel line
Whats the correct fuel line set up , drawing for a 1924 ? Does it have to be a perfect up from tank to downhill to carb ? above or below chassi ? close to chassi ?

Re: Fuel line
I am confused. I thought the fuel line should run as straight as possible without any big dips or humps in it to afford flow problems. I routed mine next to the hogshead because it seemed there would be a longer smoother bend than routing next to the frame. Now I am wondering if I did it wrong. I used a steel line from Langs. On my post about my broken hogshead someone mentioned that it should be routed differently.

Re: Fuel line
Yep,....it should be routed differently. The book sez the fuel line should be routed under the wood block that fits between the frame and right crankcase ‘ear’. Someone will have a diagram from the Service Manual.
Well, there you go; our friend Scott supplied the illustration. I didn’t notice it before

I don’t know why I turned out this way. My parents were decent people.

Re: Fuel line
The diagram posted by JTT3 is according to the book. Most important thing is to clamp the line to the frame where it passes under the exhaust. It is OK to have a low point in the middle of the line. But there should be only one low point and the line should go uphill from that point to both ends so that any air or vapor bubbles which could be in the line will rise to either the tank or the carburetor. otherwise if there is a high point in between the two ends the bubble will stay at the high point causing "vapor lock".

Re: Fuel line
It seems like this question is posted at least twice a year! I guess some just don't read the forum!

Re: Fuel line
That's OK. To some, this question is a new one. Also, some have not learned to find old posts on the forum. Like me. I was able to look up things on the old forum, but then a new format was started. It's hard to teach an old dog, new tricks. I guess I am an old dog. I don't mind seeing and responding to posts which are repeats of old ones.

Re: Fuel line
Even old, frequently discussed posts, can generate new conversations, ideas , concerns and questions, such as mine.
By owning a 1926 “Improved” coupe, with the tank mounted high up in the cowl, I don’t have the problem of such a shallow decline from the underseat tank to the carb. This said, does the heat from the exhaust pipe cause a problem or potential fire hazard? I know my pipe gets very hot. As a precaution, would a pad of asbestos insulation between the pipe and fuel line help to keep the fuel line from getting too hot? It seems like the danger would be most prevalent after the car was stopped following a long, hot drive, when there was no longer any cooling air blowing under the forward moving T and the fuel remained stationary in the fuel line, close to the hot exhaust. Not so much during the drive, when the fuel would move continuously through the fuel line thereby keeping it relatively cool. Seeing the fuel line so close to the exhaust just makes me uncomfortable since I do have a, not yet restored, 1926 Fordor with an underseat tank on which this condition will eventually need to be addressed when I can find the time to restore it, but at 67, I need to get to it before I’m completely wore out.
