The hoses on my Wagner auto pilot were "weeping" so I thought I would change them out. Nothing to it, right? Broke a 1/4" street ell while removing one hose. Had to remove the pump and take it home, where I tried an E-Z out to no avail (surprise) and had to use a tap drill to remove most of the broken part and dig the remainder out being careful not to harm the aluminum parent block. Ran a pipe tap in and installed a new street ell. Now to put the pump back into the system and get the wiring right. Ya gotta love them digital cameras for makin' 3 D schematics.
