Actually, the best place for the shutoff is before the pump... Should you have a runaway pump (ecu failure) and it runs at full pressure, instant shutoff at the valve could burst a line (has happened!). Much safer to kill the supply than the pressure
Hi Todd,
Yes, that's a good point...but in those circumstances, I'd be inclined to kill the pump supply (ie turn the ecu power off) in the first instance anyway!
I prefer to put the tap after the pump so there's less chance of air ingress due to suction drawing air past the seal (unlikely, I know, but worth a thought). Whatever you choose Arden, put the filter last in the line (no point in having it otherwise!).
Cheers,
