There's no problem that a homeowner dreads more then when he has to repair the plumbing. In my experience, the problems that require a professional to come out to your house could have been avoided by simply having it installed correctly the first time. This couldn't be more true when dealing with your race car. If you don't plumb the car correctly the first time you could be looking at an expensive repair bill that could have been avoided.
For our asphalt project car we need to plumb the oil, fuel, and water lines. To do so we are going to need 8-, 10-, 12-, and 16-gauge lines with all of the fittings to fit each line. We chose to go with Earl's performance plumbing to showcase a few new products that could make our lives easier when we plumb the car.
For our fuel line we chose to go with Earl's Pro-lite 350 hose because it's extremely durable and will resist crimping. But it's also 50 percent lighter than its normal fuel line. There is always a lot of fuel line in a race car and its weight can add up, if we can save weight here and not compromise the safety of the driver, then we want to take advantage of it.
The fittings we'll be using are Earl's new Ano-Tuff fittings. These fittings use a unique military spec hard-anodized coating that actually penetrates the aluminum for superior wear, corrosion resistance, and resistance to thread gauling. This can be extremely important if you ever have to hook up a fuel line at the track in a hurry.
In our ProCup rulebook, the maximum length of the fuel line is not specified. So you might notice in some of the pictures that our fuel line wraps around the underneath side of our car. In homage to Smokey Yunick, we did that on purpose. The extra full line will allow us to carry more fuel on board, in turn we can go farther on a full tank of gas. A typical race in our series will run 250 laps at a half-mile track. Now we can't make all 250 on one tank of fuel, however, by putting extra fuel line in the car we might be able to extend our fuel mileage to 235 laps. So our strategy would be to pit early in the race, say around lap 15, and get our fuel stop out of the way.
