I have a Howell TBI Kit "offroad" that I installed on my 4.2L I6 about 6 months ago. I bought it brand new and it works absolutely perfectly. Problem is that my 4.2 has no oil pressure and I have decided to go diesel.
So I have the complete kit with fuel pump, TBI, computer and wiring harness. I also have a cold air intake that I bought for it as well. Everything works perfect. If you are interested, please make an offer. I paid $1,200 for the TBI kit and $90 for the cold air intake. I know I am going to lose money, but it is only 6 months old and works perfect... So serious offers only.
