It’s probably more a matter of pressure mart. When you add hose you increase the total volume inside the closed system. Then it takes more volume of air in and out each stroke to generate the same pressures you had with the shorter hoses. It would be the same thing as going to a larger length and diameter receiver.
You could probably remedy that by switching the push rod position on the fly wheel, as if you were setting the machine to accept a larger receiver. Probably the next hole up, maybe 2. But once you had it set, you’d always have to use that longer hose. If you took it off, you’d be pushing too much air instead of not enough. Pop off city.
You can probably add maybe 2 or three feet and not notice much of a difference, but a 10 foot section, you’d need to adjust the machine for that.
