Thanks for the clarifications XVIPER. BTW, I did cycle the ignition, i.e. fuel pump, many times before making return trips to the gas station. As I mentioned, I also attempted to jack up the rear of the car in an attempt to level it out. Neither of these worked until I added the third gallon of fuel with the rear of the car jacked up.

Anecdotally, modifry said that this has also happened to him a couple of times.

 

I heard of your fun at TGPR Yakrat. Your car may use a bit more fuel than everyone else does per lap. I'm amazed you didn't have any misfires when the tank was that low.

 

Now you have my curiosity up. Can you describe the nature of the incline that you were parked on and the car's orientation on it?

 

Hey Chris,

The car was definately tuned rich, so I should have payed more attention to the fuel light when it first came on. I am grateful that I came off the track in time to let the engine and turbo cool sufficiently before it ran out of fuel. It was a fun day.

Xviper,

I was parked on an incline on the right shoulder with a bit of a right lean. After putting the first gallon in the tank, I jacked the car up at the right rear jack point effectively nullifying the rightward lean. It would be useless for me to attempt to estimate the degree of inclination. Though, I can say that it was not sufficient enough for me to roll backward with atleast two of the four tires on grass. Moreover, two guys even attempted to roll the car backward to a more level surface. They were unable to push the car with me at the steering wheel.

 

yakrat, It's actually pretty common for people to run out of fuel a TGPR.
The tank is centrally located, but the pump/pickup is on the left side. Leaning to the right definitely didn't help you out.

What fuel pump are you using? A walbro in tank pump? If you are, I would be careful of the angled filter sock included with some of them. When I installed my Vortech's (Walbro) pump I didn't feel comfortable with a pickup that wasn't flat with the tank floor. I reused the original. The angled pickup also can block the sending unit's float, messing up the gauge reading.

This is at least the 5 time I've heard of it in the past 2 years. It doesn't help that the nearest station is several miles away.

Skip Ferrari ran out of gas last year, and swerved the car back and forth to keep the fuel pump pickup covered. He sputtered all the way to the station.

I hear that Modifry had quite a time trying to give your turbo car a run.
Good to hear you stayed in front.

 

I'm using the pump that came with my comptech supercharger kit years ago. I do not recall the type of pickup that it used.

I hear that my best time was in the upper 1:12's. But, I was definately getting faster as the day progressed. One of the reasons that I pushed the car to empty is that I was gaining on Modifry. Another lap or two and I might have passed him ... but I ran out of fuel. Anyway, Modifry was fast with his Hoosiers until they were corded. I need to try them one day.

 

I'm pretty sure the Comptech SC uses a Walbro pump. Not sure what pickup is used though.

 

I ran out of gas after a track day (twice actually) on the way to the station. Stopped on level ground and attemted to crank the engine to see if I had anything. Not even a minor sputter, it was flat empty. Put in less than 1 gallon of gas, turned the key ON, waited about 3 seconds for the pump to shut off, and it started as if it never ran out of gas - immediately. I suppose it all has to do with the fuel pickup location, although I thought for sure it would crank more since I surely purged the lines. My car is basically stock, but I was surprised at the fuel burn on the track. Gallons per lap is a better measurement than miles per gallon!
