Brettly, good job mate, i'm in the process of doing the same thing and i to have the fuel manager to install, i have a couple of questions which u maybe able to answer for me.
1. Did u plumb urs in before or after the genuine filter ?? i ask as i have the system without the sensor, and the provider advised me to plumb it in after the gen filter, as the gen filter has the sensor built in, makes sense to me, ur thoughts.
2. Is the large fuel hose of the gen filter the hose to the pump, i havent had a good look yet, but my research tells me this is the case ?????
3. Have u had any dramas during the install and once u fired ur truck up ?????
Thanks in advance
Silver.
