Today we assembled the test manifold, to start with we are going to test the cheaper 4WREE valves, which we have two of. We will then install and the 4WRPE valves when get the rest of the cylinders and need to test the complete leg.
We asked a few hydraulic experts how tight we should do up the fittings, most of which are 3/8" and 1/2". The answer seemed to be tight.. chuffing tight! hence the big spanner!
