Snap to Connect Fitting (STC)
The STC fitting on the back of the high pressure oil pump is another weak point in the high pressure oil system. It will weaken and blow apart. The repair for this is a piece that screws into the pump with a backup nut that the o-ring is held in place with.
For any questions give me a call at (678) 920-1187.
Signs that this could be a problem are:
- Hot no start
- No start
