Fuel Line Length.

I posted about the site saveing my 12.5 by telling me what to look for.

Now I am wondering if I made the problem worse by installing the fuel line to short. The one on the mower had fallen apart internally due to methanol I guess. I put the line of my dead mower that had a cut-off installed. It is however shorter. Thus the line is very near straight across from the tank to the carb.

Over the years I have noticed that the fuel lines usually have a pronounced guppy belly in them. I had always thought that they were to close to the steering rod. Thus I shortened it some.

My question is: Is there a reason for the sagging line? I was thinking about or maybe over thinking it , and I was wondering if the up hill climb towards the carb. made for less pressure on the valve and seat?

Meanwhile I will use the cut-off as directed. Thank's to all from N. E. Texas.

makes no difference, the pressure is determined by teh height of the tank relative to the carb. the line could dip all the way to the ground and back up and fuel would still flow at the same exact rate.

more than anything i think the extra line is there just so it doesnt get pulled off during turns ect when the frame flexes because if its to short and is pulled tight there is a chance of the vibration and flexing of the frame pulling it lose and when that happens also a chance of a fire
