Stevie would you say the pressure I'm getting sounds about right? I've found a video I recorded before hand and it used to be about 38psi at idle so not too drastic a drop.

Well from the sandwich plate the hose goes to my remote filter housing that's mounted onto my strutbrace, then another hose goes from there to my cooler which is mounted next to my gearbox with a return line to the sandwich plate. Hoses are 1/2" diameter so quite large, I've read the larger the hose the lesser the drop in pressure. At first I had the hose on the sandwich plate the wrong way round but noticed a problem
Straight away and sorted it
