Like I have said in some other messages in this board, I bought a lot of stuff from a military vehicle. It had 6.2 and I am putting it in my K5. I got some stuff with it I want to know more of (was on the inner fender). I have posted some questions and pictures before and its amasing how short time it takes to get the correct answears. Now it might be a bit more difficult because I think most of those things are not very common. Its probably a part of some Artic pack or something. First, here is the vehicle: This vehicle was used to tow airplanes. 1: This is a fuel pump. It also has a mech fuel pump. I was guessing it was a lift pump. Should I use it? I know the mech pump should be enough but it might be better to have a lift pump. The guy who sold me the engine told me the mech pump where not connected, only this fuel pump. 2: I dont have a clue what this black box is. There is a plug on the harness for it so I am going to plug it in. It would be nice to know what it does, or if the engine needs it. *** This vehicle had lot of heating devices. Next photos are off some off that stuff. 3: 4: This is probably a power sourche. 5: I think this is to heat the coolant. It would be great if anybody could tell me something about it. Thanks, Jon H.
