Looking at it , I have to agree with You , It looks like it would be a "tight" fit.
It probably will work but the return hose will have to be just so-so in its' location for sure.
I looked up the individual part numbers on the hoses and found out Kubota sure is proud of them on individual pricing.
The fitting to go in the block alone is almost $10.00, One hose (100") is over $100.00
Sounds like one needs to visit the local Parker store for sure /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif
BTW: I will try to take a pic of the seat belt this next week and get the film processed.(bear with me)
