Just remove the adapter, and return it to Me I will exchange it for like New 5.9 factory Rail,Or just remove the Adapter and dual line.
It is Now the exception to Purchase the Adapter separate form the rail.Again some have had problems with the installation,Something I may add to the discussion most of My products have a measure of safety involved, (You don't here that ****** rail and Relief ****** my engine)So some leaks that need to be work through are NOT the $$$$ hassle.
There are risks involved in Modding, Don't buy form Me if you don't want incur the risk.If you want some modest HP with a measure of safety I can give you that ,But if you want to GTB ( Go-To-Blow) you need to purchase somewhere else.
