Since you have a 1990 yours is just a straight pipe, I would either do what 5-90 said and get a brass nipple or do what goodburbon said and get a pipe from a 91+ XJ that is longer and bent. The pipe on your 1990 is a worthless design in my opinion since it puts that hose at a bend and dangerously close to the idler pulley. Yes though, use teflon tape to seal it up and thread it down as far as it will go.megabyte5689 said:It's not the nipple, its the whole pipe!
