I've removed and replaced both the PSE and soft close pumps, and never broken a nipple. Both cars I've got are southern, so there seen plenty of heat. The key is to get a thin end wrench between the fitting and the pump body, so as to force the fitting straight up, and not bend it and the nipple. You will be out a lot of money if you burn up the motor in the soft close pump, unless you find a good used one.
At the time I investigated this pump issue, I was somewhat panicked about the trunk not completely closing.
I wanted a quick solution. When I looked at the pump and what it would require to remove the hoses I didn't want to possibly make matters worse. I had read about the hazards, old plastic, broken nipples, $400 pump... the fuse thing seemed like the best solution at the moment.
If I find this to be a recurring issue, I definitely will try the screw adjustment, I just didn't want to attempt it that day given my circumstance.
Thank you for your excellent advice and 14 pages of info about this pump and it's functions.
I posted this info to hopefully save others some time researching this issue when they are in a panic as I was. You offered the true repair advise and I thank you. I spent at least 2 hours reading up on this before I made my decision.
Now if you can fix my wonky rear view mirror, the driver's seat belt retractor, the cupholder in the armrest, the slight thunking from the right rear suspension at low speed, freshen the paint on the lower cladding, R&R the antenna mast, install my metal oil caps for the camshafts with new valve cover gaskets(while yer in there R&R the timing chain guides), and restore all 4 wheels for me, I'll be even happier. I don't have too long a list of to-do's but it's enough to keep me busy.
