How much fuel do you use on a run. Are your fuel lines teflon.
So I guess what you are saying is that you run your exhaust out from under the car so that you don't smell the fumes.
No Teflon lines in my system. I use about 1 gallon of gas a pass and adding fuel each round is the only maintenance I do on race day. Most four day race weekends I never even remove the hood. I at one time (over 6 years ago) said I will never run alcohol. I hate the smell in tight spots. I also like the sound of mufflers on my car so it was a win win running them out to the side. I bought the tubbing for Summit and welded it up myself.
