If it's a hose that runs under the boom cylinder and into that sleeve, up into the boom, make SURE that the place that makes the hose doesn't make a hose that's significantly larger in diameter since it's an already tight fit in there. We have been through this so many times that it'd make your head spin, and I hate it every single time because it makes me look terrible. We basically have two options. Re-route the larger hose, or (2) order/install the Kubota hose which is usually 3x more money and takes longer to get. But it fits perfectly. Neither is an "acceptable" option in most tractor owners' eyes and I don't blame them one bit. But until I can find a source for a local hose maker who makes them the same OD as the originals, those are my only options.
