I didn't know what the car would so I figured to play it safe, thats why I went rich the first couple times. I had the small bottle in the engine bay pointing back at the solenoid. It seemed that the closer the bottle was to the solenoid, the more effective it was. I went to the hose shop off 49th st to get the hose from the bottle to the solenoid. I think in all this project cost me $85. I did use some of the stuff laying around the shop, but it is a cheap alternative to race gas and a performance pump .
