1997 max 700 sx oil lines with check valves .

HI all
Picked up a basket case 1997 yamaha Vmax 700 sx I cant find any info on the oil lines that have the IN LINE Check VALVEs.
there are 2 check valves I need to know where they are placed !?
Help with this would be much appreciated !!
Merry christmas ...

Check valves will have an arrow on them.
Arrow on the one that goes from the oil pump to fuel pump, should point to the fuel pump.
I don’t recall there being more than one check valve. But, I forget easily...lol
