I noticed today that my loader valve was leaking where the compression fitting goes into the valve. Looks like it would be easy to tighten... if you could get a wrench between the cowling on the engine or between the control valve and the loader arm. Anyone have a suggestion on how to do this ? All of the fittings are close together so It will take a rather slender wrench to do it. Looks like the fitting is larger than 1"
