does anybody else know what the little pipe thead nipple with the plastic cap is for
It is for a air filter resriction indicator I use them on all my heavy equipment
handy for checking how dirty your filter is
They have a more useful after market application... that would be injector port for Propane
I dont know about you... but Texas is a little dusty and by the time my guage gets into the "you need a new filter soon" its really "you needed a new filter 5,000 miles ago."
