in a few weeks i plan on getting rid of my car and buying a van, thing is i have my backpack and ill be using that while i save some cash up to get a tank for the van. my question is. Would a backpack in the van be powerfull enough to flow through 100M of hose on a reel just like a tank would?? i know these pumps are only 40psi and was just curious if it had the power to push all that way. would save pratting about with a trolly etc.
