There was never a fix, but if you make sure the rubber hose under the pump, that drains out the underside on car, and never gets debris in that tube and stays clog free that is the answer to fixing the water problem! Water runs down an it’s going go where ever it finds a channel, it’s also best to check the trunks rubber seals and channels to keep them clear of debris, so water flows as designed and it follows the correct direction of flow. I cut the bottom tip of to help keep it open more the just the original slit in it.
OK, here's a thought. Don't know why it is not the original design. Just remove the relay module from the floor of the well and reposition it to the side wall toward the center of the car, closer to the top edge. Used Gorilla faced adhesive double faced tape. Kind of gives it a fighting chance. Wiring moves OK and no worries.
While never having an issue with water leaking into the trunk, I did take a preventative measure of storing a large pile of cleaning, microfiber towels in the trunk corner to absorb any possible water leaking into that area. Just a thought to prevent an issue.
If anyone wanted to do it -really- right, the pump and modules etc - all the shtuff in that ice bucket, should be moved to the forward most part of the trunk, perhaps just behind the passenger seat. It would centralize the hydraulic lines, reduce weight what with less line and wire length, keep the oh-so-precious modules well out of harms way and put about 10 or 15 pounds more towards the center of the car.
What, did they think XLR owners were going to need space for a sheet of plywood in the trunk and couldn't live with a little obstacle?! It's all not that big and I'd wager it could all be tucked in there and still have plenty of space for the roof in the convertible position.
The current placement had to have been an afterthought or rated very low on the pecking order to General Motors engineers. It's not bad...it's disgusting. You don't put components of that weight and significance hanging down in a bucket in a trunk and so far from the center of the car, unless you're stupid or just plain lazy. Maybe both.
On the other side of things, they're probably laughing because they're still selling modules and spares - if not drowned, whacked by someone in a parking lot fender-bender or when the champagne bottle tips over in the trunk and pops on the way to the party. Planned obsolescence perhaps?
Enclosed are images of the rear rollover bar were the modules could be attched as per the present modules with somes U clamps.
Would one day doing the conversion, i would put the well modules on the passenger side because of some possible amanations from the gas filling area, as far is for the wiring it looks that it can be done without doing some cuttings.
Then the pump could be attached again to the rool bar LH driver side, as far is the hydraulic piping , I would wonder on how to get the piping re direct without making some kink on the piping.... it could be more of a problem.
