All I know is efi pumps like to blow not suck. So if it is too high it won't work properly. Also, the intakes on most are 1/2" so you would have to run a 1/2" line along your car (but at least it wouldn't have to be high pressure).
By the way, if anyone is looking for some high pressure efi rubber fuel hose, I got some from Edgeworth auto parts for $10/metre. This is waaay cheaper than I have seen it anywhere else. The only difference is it's red.
