I need to replace both brake lines and fuel lines, is it a hard task? is there somewhere I can go online to get an oversite of the job. 1995 chevy S10 ZR2 4.3 vortec w. Any replies appreciated

 

I'm guessing rust got your steel lines under the truck. Depending on how bad the fuel lines are I would replace only whats needed by cutting and replacing sections by using compression fittings.
The brake lines are a different story. They are usually easy enough to replace the lines from the proportioning valve back to the rear end anyway. You don't have to remove the old lines if you don't want but you MUST make sure the new ones no matter how you support them cannot rub or you'll end up with a new line with a hole in it.
Usually the easiest way to remove the old fittings you cant get to with a wrench is to break or cut the line and then use a socket instead. Once you have replaced the line(s) you'll have to bleed the brakes. Bottle bleeding works the best. Put a small hose (long enough to reach the floor) over the bleeder and into a clear bottle which you have already put enough fluid into so it cannot pull air back into the system. Keep your master cylinder full and pump the brakes until nice clean fluid comes out with no air bubbles.

 

yea I did the brakeline job sure hope I never have to do that again what a
bi-ch of a job. I ended up taking the bed off which is pretty easy to do. It made it a lot easier. I replaced the shocks while i was at it. Thank for the reply
