 +====== Custom Bends Using Copper Tubing ======
 +When changing to a different petcock or fuel tank, sometimes the lines are difficult to route and still keep the kinks out. \\
 +It also may be difficult to keep the rubber lines away from the hot engine. \\
 +Straight copper tubing can be used. \\
 +But this idea will cover up the copper and keep the black tubing look with the advantage of strength in the bends. \\
 +This was done using 1/4" copper tubing. \\
 +
 +  * Simply cut a few short pieces of copper. ((photos by Jtrapass of the XLFORUM https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/65004-fuel-line-routing?t=411605))
 +    * Make the initial lengths too long so the bender has plenty of tubing to bite on for making the radius.
 +  * Then use a tubing bender to make the bends you need.
 +  * After bending, cut the radius down to make a short enough bend so you can thread a rubber hose over it.
 +    * **Note**: Be sure to de-burr the ends and file / sand them smooth before inserting them in the rubber hose.
 +    * When cutting copper, the ends will most likely have a lip left over that'll need to be filed or sanded off.
 +    * You can also use steel wool on the outside of the copper tubing to make the whole bend smooth for insertion.
 +  * Any lips or uneven edges can eventually rub a hole in the hose so it needs to be smooth.
 +  * The tubing should stop at least an inch or so before each connection to allow the hose clamps enough room.

 +  * After inserting the bends in the hose, cut the ends to length and install as usual.
