2002 VLX Rear Ballast Pump Replacement

[jvianco]

So after 19 years, one of my rear ballast pumps has started to fail.  I have replacement pumps for both already, but I'm having issues trying to get something to grip on the old pump to break it loose.  There is minimal room where the pump is located.  Anyone have any tips on how to access the rear pumps more easily?

I use a strap wrench on stuck pump rings.  Work of caution be sure to remove the set screw and little blue stop block or you will not be able to loosen the ring.

Mine didn't have a set screw or a stop block.  I ended up getting it out by using a little hand held hack saw and cut off the pump, and then used the saw to cut two vertical lines in the leftover threaded PVC, stopping just before it got to the brass threads, and then used a screwdriver to pry out the cut section.  After removing that little section, the remaining piece came loose very easily.  It was a tedious job, but both rear pumps have now been replaced, and will hopefully last another 18 or 19 years, and if not, the new pumps have replaceable cartridges.

That is crazy.  You live not far from me so anytime you need help let me know.  I am one of those weird guys who love to work on cars and boats.
