Heres a diagram a fellow Pelican posted a while back. Perhaps this will help.....
I believe this is for a Mid-year CIS vehicle. Screen/drain plug is on the bottom center, The supply from the tank to the pump is the large slip-on 11mm hose w clamp on the left. The threaded fitting on the right is the return to the tank, probably M14x1.5 though later years used M16x1.5 I think.
Absolutely a good idea to move the pump up front for many reasons. I can help with Metric fittings & new multi-fuel Metric hose if needed.
