seadoo - leaking preasure regulator

96 GSX Seadoo

Leaking pressure regulator Assy.. I replaced the inside with a used one =
and was told to use wd-40 on the rubber to keep it soft. Did I do more =
harm than good?

It is still leaking from around the top of the assy. This fill the hull =
with water, naturally.

Can you help.

WD40 claims it doesn't harm rubber. A coating of oil or other petroleum-based products, OTOH, will eventually cause the rubber to fail. Did the instructions call for lubricating the rubber? Sometimes it's best to not lubricate (as is the case with many rubber gaskets).

Just out of curiosity, why didn't you replace it with new? In more than 30 years of owning and maintaining boats, I've never had any success with used parts. They either don't work properly or fail soon after they're installed.

Had someone who had the inerds and gave it to me. I guess you get what you pay for. Is the rubber suposed to seal it and the 4d-40 is preventing a good seal?

Thanks for your thoughs

I'm not sure what regulator you are talking about but the lube is unlikely to be causing it not to seal. I would check the mating surfaces of the o'ring.

Even if it were to brake down the rubber it would take a long time.

the old one had a metal piece that held things together that had rusted, I did clean the surfice that it would seal to. It had some rust on it. I will check it again.

Thanks

Re surface and use grease on the o-ring, not wd-40.

Tried and that did not help. I ended up having to replace the bottom casing along with the rubber bladder. That solved it.

Thanks for all your help.
