What size bolt to plug AIR holes in manifold
Got tired of needing a blood transfusion everytime I changed plugs or worked on the engine. Gutted the pump and air system. What size bolt do I need to track down to plug the holes in the manifolds? Thanks

1/4" NPT plugs . available at most all hardware stores . i would suggest the ones that are internal/allen wrenching . they just look better , i have used them in the past . good luck .
