Default Pressure dropping fast after runs..

Im using a wet kit with a 10lb bottle, and a 175 shot. There is 30ft of total line 15 to the solenoid and 15 to the gauge, would a leak cause the pressure to drop from 1100-800 in 1 gear? The bottle is definatley full and the bottle heater is on.

I've noticed that my bottle pressure drops really fast as well. The first spray really hits hard, then it goes down quickly from there. If I spray three times in a row from 1100 PSI, you can definitely feel the difference by the third time. Is that normal?

WTF do you have 30' of line? last street pass I dropped about 200psi going 1-3. m6 6an line 250 dp jetting. I have 1 14' 6an line. Maybe some will agree but nothing better than that first hit on a fresh bottle.

Here's your cure for bottle pressure drop per run; dual 15lb'ers and dual heaters.

Most of the guys that are serious and want to maintain a 10lb bottle for weight factor usually change the bottle out each run.

Pretty much what Robert said. I only get two good runs per bottle. The Third run is always a crap shoot no mater what pressure you start at

I have had issues with over filled bottles and colder weather. If there over filled it doesn't take much to get them up to pressure with the heaters. Then when you spray mine seem to drop really fast. After I use a bit out of the bottle the pressure stays pretty stable
