looking for part numbers or links would work, thanks in advance.

1. Fuel/Injector line - time to replace the old rust line. Not sure if the plastic round lines need to be replaced, but definitely the line going across. May also replace the fuel injectors themselves.
2. Fuel tank/cover bolt 🔩 its a special bolt
3. Is replacing the head gasket a huge task and does it require any special tools? I definitely need a torque wrench.
misfire cylinder 8, already replaced wires and coils. Also, recommend anything else to get done while replacing the gaskets?

Thanks.

 

most of your queries require the year on your truck. even if you where asking at an auto parts they would ask the same.

 

No need for part numbers!
1-Replace the steel fuel lines with nylon.
2-Nothing special with the bolt.
3-Only a cylinder 8 misfire?=fuel induction cleaning.
