There have been many times where Lenny has been able to fabricate items out of found/free items people were so ready to walk away from and discard.
To start Lenny took the old injector line and cut off the flair in order to remove the bushing and nut to use on the new line.
Then he started to mock up the 5/16" break line by making the needed bends but making sure to leave enough extra line for final fitting and new flaring. He used a line bender, he also found in a rental cleanup, for bends and will be using a break line flare tool he picked up for a few bucks from a local auction for the flares.
Now there are those gaskets. You would think coming from the factory the flare would be adequate but there are also rubber gaskets in the nuts. For the gaskets Lenny has taken some spare 5/16" diesel fuel rated fuel line, left over from a previous return line project. You need to make sure the line you use is a pure rubber line with no nylon in it because it may not allow for an adequate seal. If the line is not diesel rated the new gaskets could be eaten away by the diesel fuel. Using a pair of dikes, he cut a quarter inch of line for the new gaskets and placed it on the break line for a rough fit.
