I use the 3/16 inch clamps on the reserve line - cut the tabs off after connecting the hose to the fitting and moving the clamp up to secure - seat the bushing in the tank push everything down snug then drive it home with a BIG HAMMER the hose clamp will go through the bushing even without grease.
I've had good luck reusing the clamp type from John Deere for the rest of them.
