plastic fuel lines
I read how to heat plastic lines to press them on the barbs. does anyone know how hot the water needs to be, and the cooling process ? thanks for any answers.

Sounds like it would be hard to use hot water, especially when the lines are in the engine bay or under the truck. I don't know what the temp should be.
I just went through this with my 86 ranger when I pulled the engine. I didn't have the right tool or something, but I could not get those spring girdle connectors to come apart. What I ended up doing was heating the line with a heat gun till it got soft enough to pull it off the barb. This pretty much ruined the line on the end, but I had enough extra where I could cut it off to a good section.
When I went to put them back on, I found the heat gun would get too hot and mess the line up before I could get it on there. Heat also makes the line weak and it folds up instead of being able to force it on the barb. The trick I found was to take the heat gun and heat the metal barb. Then lay the gun down and take both hands, one on the line and one on the barb fitting and quickly push it up on there. The hot barb seemed to soften the line up enough to get it about halfway up on there. I then used a small hose clamp around it for extra insurance. It hasn't come off yet, been using it for about 3 months now.
