Ive got my bottle mounted in the spare tire wheelwell so ive got quite a bit of line. Also about an extra 3ft curled up where the air pump was under the hood. After i turn off my bottle how long should i expect the lines to hold pressure? The pressure will be at about 1100, ill shut the bottle, park the car, come out the next day and ill have empty lines with no pressure. I know its not good on the solenoids to leave that kind of pressure in, but im just wondering if i have some sort of slow leak. I tightened all the fittings and whatnot pretty good with teflon paste. I cant hear a leak but that doesnt nessicarly mean it isnt there. Does it evaporate completely in the lines over 10 hours or so or do i have a small leak?
