has anyone else added a quart jar of gas to the vacuum lines of the car???? i did and got about 7 mpg increase on my 1997 jeep grand cherokee the only bad thing is that it only really gives my the gains in economy if i hold a sufficiant amount of vacuum. I have a 8 gallon compressor i modifide to fit under my jeep that i'm going to fell with 5 gallons of gas and i want to add a 35 inch pound vacuum pump to it and have a ball valve to control the amount of fuel the pump sucks out by connecting the ball valve to the throttle so i have gains throughout the throttle position.
