RB20 Oil pump location?

[Wojski]

Hello Everybody once again my oil pressure has an intermitent low pressure reading. I have heard a couple of things about the bolts of the back of the pump being loose and was just wondering the werebouts of the oil pump on an RB20. i am only new when it comes to knowledge of the RB20 and info would be greatly appreciated. i dont like these low oil pressures and also i notice when the oil pressure goes low at about 4000rpm i hear a very weak knocking noise which sounds very minor although it only happens on the low oil pressure but when the pressure rises again it dissappears. thanks
