Help 4320 and 630 tractors

[williaada]

Need some help with my two Deere tractors:

630- lost the gas cap and bought 2 new ones from Deere. the cap continue to leak gas when the front is tossed around. I have replaced the cork gasket multiple times. Any idea on how to stop the gas from spilling out the top?

4320 one of the hydraulic outlets on the tractor will not lock in the hoses. What are my options to fix this, and what seems to be the best solution?

I suspect the 630 filler neck is cracked where it attaches to the tank, seen that several times on these tractors.

Do you have the correct hose ends for the outlet. Just asking cause it happened to me before. Assuming the barrel is sliding back and forth in the housing properly. Does it slide back towards the tractor to lock the hoses. Away from tractor to release.

You need a non vented cap. The 20 & 30 tractors had a vent line on the tank.
