Valve covers on... Front main fixed. Just need to weld up the e vap deals from vibrant.

Have two breathers in each side on valve covers.

same fittings i run on all my trucks they work awesome

Some people have been telling me to get one way check valves on them... I don't see a need why as they are under vacuum? Would soot and pressure really get up into the lines and into valve cover? I just can't see that happening.

The one way checks are for gassers incase of a backfire.
