Since oil isn't really that compressible, it shouldn't be an issue.

Other options...

3/8" Pipe Needle Valve
This one is rated for 18 GPM maximum flow too.

Another version rated for 13.5 GPM.
3/8" Pipe Needle Valve

Other sizes...
Colorflow Type
Knob Type

My tractor only flows 6.1 gpm at valves, so what I have should be big enough.

I sure thought the pump flow was 7.6 GPM. Your manual may say different.
