Super important fella's. Be sure to get Glycerin-filled gauges and the lines are ethanol gas resistant. The gauges noted in the video are definitely Glycerin filled, otherwise the gauges tend to bounce around and it becomes hard to get an accurate reading. I have an email out to the manufacturer of the lines to see if they are gas resistant. I have only used them a few times and didn't notice anything immediately but the hoses could deteriorate over time. Also, these lines are only good to 120 PSI and so far they hold pressure at 110 to 115 no problem. It would be good to have them able to handle to about 160 PSI just in case. But anyways, thought you should all know.
