Model T Ford Forum: Forum 2014: Fuel line question

The fuel line on my 25 at one point is only about 1 inch from the exhaust pipe. Is this acceptable or does anyone have a picture of the correct configuration for the frame mounted tank line? Harv.

I'm still kinda a newbie here Harvey, but from what I've read on past posts, 1 inch should be okay...that's plenty of air space to keep the line from getting too hot. You don't want it any closer though, it may cause vapor lock.

I agree, 1 inch should be fine. The previous owner of my car wrapped about 2 feet of the exhaust pipe in the area of the fuel line with header wrap. Not original, but it does help cut down on the heat in that area. :-)

If it's going over the exhaust pipe, 1" is too little. If it goes below, it's a bit tight - if it works it's OK, I suppose, but I would have tried to get more clearance.

Ford recommended to route the fuel pipe over the exhaust towards the frame, then forward to the carb along the frame. But that was when Ford made the exhaust pipes. Repro exhaust pipes are usually not the same so you may have to route the fuel pipe along the transmission under the exhaust. Fasten the fuel pipe along the way so it won't crack from vibration.

There is a diagram of how it is routed in a service bulletin. I believe Dan Treace has posted it several times.
