Take the guage off of your inline Reg, and plug it with the plu in your LP Reg hole. Then take that guage, and put it in your LP reg hole. Use that to set your preassure. After you have your preassure set take your tank off. Then take the guage back out of your LP reg hole. and the plug out of your inline reg and put the plug back in your LP reg hole and put your guage back in your in line Reg. That would be one way to do it without buying any other parts. LP Reg set at 85 psi.
That is so simple I can't believe I didn't think of that. But it looks like the local store owner is going to let me use one of the gauges off his shocker to set it.(was just talking to him 30 min ago and ordered my timmi)
