Not Looking Like a Factory P/S Hose Arrangement

Can't help w/coller pin issue but the rest seems standard issue. The factory pressure hose is a two-step affair designed to reduce internal turbulence, yours looks correct. The low pressure return hose on yours has been modified. These boxes have two different hose sizes and yours has been adapted from the larger one down to the smaller one. Probably you will need to replace the box's top valve hose adapter (just the end fitting that adapts to the hose) which will reduce the hose size to mate to your pump fitting. Then you should be good.
