There are three of these !
Part # 028-130-431 Holds each of of two Line's ( 2 Required )
Part # 068-130-421-A Holds the complete set of four Lines ( 1 Required )
These keeps your injector lines from breaking
My pump and new 155 Injector Assys go off to Giles and he will clean up the lines and I think it's a good time to replace the Clips.
