If you got that then no problem prefilling them.
The electric pumps were nice, hit the key wait for the pressure sound, and start.
The old way of doing fuel doesn't apply to the newer tractors for sure.
I believe that's why some guys have so many fuel related problems.
We always do it this way, never had a problem before.....
Why do we need this fuel lube, my dad didn't use it...
