Default Re: Fuel change from VP to Sunoco

I swap fuel frequently throughout the year because I have no place to put a drum, so I buy whatever's at the track. I've never found C-12 at any non-LODRS/Nat'l event, so whenever I'd go bracket racing, I'd end up with a mix of stuff, then have to go through the process much like Mike describes every time I went back to an NHRA event. My car's fuel injected, so I'm dealing with a return line, but use that to my advantage. With the power off, I turn on the fuel pump switch, disconnect the return line at the fuel cell and connect a temporary piece of line to run into a fuel jug. I use the master cutoff switch to run the pump until the cell is *almost* empty (don't run the pump dry!) Add a splash of the fresh gas and pump it down again to make sure the return line is flushed. Fill, and reconnect return line, go race.

The only time I've ever had a problem was one time with the Turismo. I learned that with the stock fuel tank, the pickup was a little higher than expected, so it wasn't flushing enough of the tank. The next time, I backed the car onto the trailer ramps to get it nose-down enough, and never had a problem again.
