That 'plunger' actually went to the solenoid. I took it out from above. I can't see anything from above, but still I would try. That's also why I broke that line (not seeing well) I removed part of the lift pump without taking the line off first. I thought that it WAS the line. I could feel the spring of the line as I turned it, but I thought if it is stuck, then it will have to be broken anyway. If I had looked closer, I would have seen that the actual line had a nut in the center of the part of lift pump that needed to be loosened.
After I pulled the lift pump, I got out from under the truck. I was trying unsuccessfully to see down from above, when I noticed the solenoid piston (what I later took to be the plunger) I took it out and assumed that it went to the fuel pump. The solenoid, at this point was nowhere on my mind.
Funny thing is, I almost got the 'plunger' into the lift pump hole. I put it in at a downward 45 degree angle, but it protruded a little bit. I knew that the (real) plunger on the lift pump would be compressed while tightening the nuts, but this was too much. I also could not get the spring on the 'plunger' either. So I got on the TDR and asked you how to get this darned thing in, and you responded with the picture.
Kind of embarrassing. I was in a hurry and couldn't see well and assumed too darn much-I 'knew' what was the problem!
