How much torque for 22re fuel line banjo bolt?

There's no single definitive torque specification for a 22RE fuel line banjo bolt. The torque value depends on the size of the banjo bolt itself (its diameter and thread pitch). Toyota's service manuals don't always specify torque values for every single bolt, especially smaller ones like banjo bolts.

Instead of relying on a specific number, you should follow these guidelines:

* Consult your Toyota 22RE service manual: This is the best source. Look for diagrams showing the fuel lines and their connections. Even if a precise torque spec isn't given, it might suggest a general tightening procedure.

* Use a torque wrench: This is absolutely crucial. Overtightening can easily strip the threads or damage the banjo fitting. Under tightening can lead to leaks.

* Tighten snugly by hand first: Get the banjo bolt started and tightened by hand as much as possible. Then use the torque wrench.

* If you can't find a torque spec: Tighten the bolt to a *moderate* torque. A good approach is to tighten until it feels snug, then add another 1/4 to 1/2 turn *maximum*. Do not force it.

If you're unsure, it's significantly safer to under-tighten slightly and then check for leaks. It's much easier to add a tiny bit more torque than to fix a stripped bolt or a cracked fitting. Consider using a sealant on the banjo bolt threads as well, as per the workshop manual.
