SHURFLO Complete Upper Housing with Switch & Bypass (Model 4048)

This SHURFLO replacement part is a complete upper housing assembly with the pressure switch and bypass already built in, made for the SHURFLO Model 4048 pump. Swapping the upper housing restores proper pressure control and flow when the original assembly wears out.

Rebuilding with the correct housing is an economical way to get a tired pump back to spec instead of replacing the whole unit.
