You could still lose fluid from a ram etc and it wouldn't necessarily show as a change in the reservoir level until the hood has been operated a few times and it's purged the ram etc of air.

I thought of this and I purchased replacement rams. When I was ready to start work, both units seemed bone dry, so I aborted the work and that’s when I removed all carpeting from the trunk and started diving in from that side.

I daily drive this thing and the top gets used often.

Probably time to get the tissue paper out and start wrapping all the parts of the Hood system to find the leak.

Between vacations, and kids back from school, it's been challenging to find time to work on the Jag, but I ended up dumping in a fuel dye and my trunk has lit up like a Christmas Tree with the black light. It most certainly is the fuel tank.

I have to take this back to the shop that I had seal coat the tank last year. Will keep everyone posted.

Talked to the shop yesterday. WIthout getting a lot of detail, the tank was not leaking, but there was some kind of failure at the purge system. Somewhere between the charcoal canister and the tank was the cause of the leak.

I'll share more details when I go to pick up the car, probably Monday, for anyone concerned.

I'm a bit updet at myself for getting so close to spot the problem. Once I added the dye, and saw that dye in my trunk, I immediately assumed it was the tank and took it back to the shop that sealed/refurbished it for me two years ago. I should have taken one more look at the tank with the plate removed to find the actual source...ugh
