I broke a tilt bucket hose on my New Holland L35. I thought it was 1/2" (app 20" long) but after buying one from farm store that fitting was too big. I then tried a 3/8 and that was too small? that was the only sizes they had in various lengths. Is that hose Metric? it does have a '8' on side of nut you turn. What about 7/16? Thanks for any help!
