Phantom Posted February 17, 2006 Share Posted February 17, 2006 Regarding keeping the tank 1/4 full: when I autocrossed my 240Z with the stock fuel tank I could run it down to 1.5 gallons and still not have fuel starvation problems. Obviously there must be some significant difference between the 240 and the 280 tanks. I was encountering fuel starvation accellerating out of hard low speed turns when my 280 tank dropped into the 4-5 gallons remaining range. I got my first hint of it when I was at about the 3/8 full mark which, on my car, would be about 6 gallons remaining. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 17, 2006 Share Posted February 17, 2006 If John was running carbs, then the float bowls act like little surge tanks. There is no fuel reservoir on the FI setup, so they are more particular about running low and if they suck air air gets into the system. In the carbs the air just goes out the float bowl vents and it's like nothing even happened so long as the fuel pump can refill the bowls before they run dry.
