We have been running at Bonneville for 40+ years now...... we are usually very careful about making sure we have lots of fuel. Until we needed to make a water tank out of our original (not stock) fuel tank, we had a 30 gallon tank in our Vega.... It did NOT run out of fuel..... We now have an 8 gallon fuel tank and it is always a worry about whether or not we can make two full runs with warmups and all. If the tank is full, it will...and we have never run the Vega out of fuel.
The lakester now... it has a 10 gallon fuel cell .... we fill it quite full as well..... the first year we ran the lakester, we were licensing two drivers.... we had got the second driver up to a 190 mph+ B License run.... we were doing laps on the short course on Friday morning .... and .... someone's (NOT mine) "famous last words" .... "We are only running for 3 miles and not at full throttle- SURE it will make another run!!!!"...... well he was coasting at the 2 1/4 mile at 185 mph.... and we ran out of time to make that A License pass....
So, even with a big tank keep watching the fuel consumption.....
There is one other thing I must add..... and another case of "famous last words" are part of this one as well.....(it was the same "someone" as well) If you are running in ANY GAS CLASS- unless you know that you are only doing license passes or your engine is 300 hp or something under what it will take to set a record- GET YOUR TANK SEALED! .. with the Vega back in about 1999 or 2000..... (here come the words).... "NAW....NAW.... The car won't be able to qualify for the record.... we are just going out for a test pass!".... the record was 237.833 mph..... the car went 240.959 mph!..... WITH AN UNSEALED TANK!..... the next run would have made a record 2 way average..... but was short of being a qualifying run (at about 234.950 moh)..... and we hurt the motor bad after that.... It took until 2003 for to set that record and get our third team member into the two club.....
