My 93 T-100 sprung a leak from the return line ( i think) from the ABS actuator to the power steering resivor. Simple little low pressure metal tube about 8" long held on with one 10 mm bolt . Tube rusted out and was leaking. Called the dealer and it not available seperatly!! Only available with the actuator- About $800. I patched it temp. with a rubber hose and aclamp. Went online to a national junk yard finder service. After sending out about 20 emails with a pic from the shop manual, I found the tube in Nebraska for $20 shipped!! Took about 5 min to change. I love my truck but rust is slowly killing it.
