How long of a hose can I use effectively without losing much suction on an 8 in. diameter hose from a TracVac 11HP hitch mount unit? I have the standard 12 ft. came w it and works fine, but by the time u get turned 90 degrees and to the side of truck, there's not much hose left to suck up leaves. I mean, I have to blow most of my leaves all the way to the curb. I could save some time if I had longer hose, maybe 25-30, even 50 ft, but don't want to spend small fortune on hose only to find I lose too much suction. Any advice? How long has anyone run 8 inch hose from 11HP unit and still had good suction? This hose is too expensive to buy and guess. Why I'm on the topic, anyone know a good source for hose 8 inch diameter? I found sources from $15 to $25 (plus high S&H) per foot. I'd love to pick up a used one.
