Leak in hydraulic line for rear jack

Line came in 2 days later. The removal of the old line and installation of the new one was relatively easy. It took about a quart and a half of transmission fluid to fill the system. I did not bleed the line just cycled the jacks about 6 times. I split a section garden hose to wrap around hyd line where it crossed over frame members. In general I like this HWH system, it is 21 years old and so far I bought and installed a control board for $100 because I left the window open and it rained in on the board and $67 for the hose which leaked do to chaffing through the outer covering into the steel braid. Both of these failures were preventable. RH front jack sometimes does not retract but spraying it with silicone spray once a year eliminated that problem.
