Rusted brake line replacement

[Raptor King]

Replacing rusted out brake lines with Dorman Stainless Steel pre bent brake line kit. Do I have to drop fuel tank and driveshaft as suggested in their video ?

It's my understanding you need to either drop the tank or lift/tilt the bed to replace the rear line.  The line runs along the inside of the driver's side frame rail, and there's no clearance to change the line without doing one or the other.

 

You might also consider replacing the fuel pump unit in the fuel tank when doing this, if you haven't changed it recently, as it's likely due to fail anytime soon.  And don't forget about the fuel filter as well (inside the frame rail under the driver's seat).

I didnt drop the tank or lift the bed when i did mine, it took alot of wiggling and having a friend help but i got it through.  It might not be sitting exactly where the oem line sat but its possible to get it done.   2007 Sierra 2500 classic with extended cab 8' bed.   By far was the best choice I made, took me about 5-6 hours to put the whole kit in. Make sure you either have a scan tool or a friend with a scan tool that can do ABS automated bleed or else the pedal wont feel right. If you need I can copy the information onto here of an inexpensive one i bought that can do the Auto Bleed.
