Fitted up my sandwich plate ect for my cooler and the oilstat arrived today

Dose anyone know which hose is the feed to the cooler and which is the return?

I have spun the engine over and it looks to be the rear hose which is the feed as it fills with oil but the front hose also fills up but at a slower rate

Got to get this right as its going to be a nightmare to get to once the head is back on the car.

Heres a pic of the plate and hoses.

Any help apreciated.

Cheers

Paul.
