After taking the leap with excel aux tank- my opinion the long ranger would work just as well, maybe even better with slight modification in the installation process. My only issue I have with excell is filling the tanks is a little bit process especially when using a pump at a station that does not have vapor recovery system. In these cases I have to wait for the air to escape from the system to continue filling the tanks around the 24-gallon mark, when the main read 1/4 I normally add around 30 gallons, adds a couple of minutes to the fueling process. A small sacrifice to have a 450 plus HWY range. As far as the EVAP relocation, I found a proven method that does not require extending the wiring harness or the plumbing hoses. I have not really have any issues to report and passed emissions with out issue.
From what it looks like the Longranger as designed right now would actually introduce a leak into the evap system in the USA models that is why I went with the excel. We have an active evap system in the US while the rest of world seems to a passive evap system. What I mean by active one that runs test cycles under defined parameters to meet clear air regs. The URJ200 us spec runs an evap test when the main tank is between 3/4 and 1/4 full and under a certain pattern of drive conditions, it tests both pressure retention and vacuum of the closed loop system.
With experience with the installing the excell and reviewing the long ranger youtube and written installation instructions- The issue I see with the long ranger system the transfer pump is not valve and will result in introducing an air leak into the system. I would hypothesize one could use the Long Ranger with a slightly different installation approach. -
1) follow the excel tank process of installing the gravity fuel fill into the main tank, which means dropping the main and install a threaded fuel hose connector, connting this to the Long Ranger Fuel transfere pump 2) install a fuel solenoid value as close you can to the fuel fill point on the main-
The theory of operation is the solenoid will close system when fuel is not being transferred and truly isolate the main from the aux system. Before fuel transfer, one one would flip the switch to open the fuel solenoid, and then flip the switch once the fuel transfer is complete to close the valve and hence the evap system. Having separate fuel fills would speed the filling process, and one could use the aussie EVAP canister to have a passive vapor collection from the aux tank.
Good and interesting info. So you're saying the big question is whether the LR supplied pump seals the hose in the "off" position in order for the system to pressurize properly? Just speculation, but if there's fuel behind and after the pump in line of the transfer, the pump wouldn't leak air. Maybe though. Once this house sells I might just end up purchasing one to see if I can make it work. Assuming I have funds after my gear/locker installation.
