New Bosch injectors for my 1990 Jeep Cherokee XJ I6 4.0L I cut out the old EV1 connectors and installed EV6 connectors. Replaced the fuel pressure regulator as well. Most difficult part was the o-rings for the fuel lines, supply and return. FSM states that these should be replaced upon dis-assembly. Be prepared with o-ring kit #83502745 from dealer.
