Removed my UPR catch can

[bwilly68]

After using my catch can for a few thousand miles I have pulled it from my vehicle permanently. When I first installed it I noticed a small amount of liquid inside after a thousand miles. I also noticed a persistent smell of fuel and oil in my garage that I didn’t associate with the catch can at the time. No smell in vehicle cabin. After reading some conflicting opinions about the necessity of catch cans in general I removed it and returned the truck to stock. It was then I noticed that the smell of fuel and oil in my garage was gone. I waited a few months and put the catch can back on. Double and triple checked the installation. All visible o rings and hoses appear intact. Lo and behold my garage reeks of fuel and oil again. It’s bad enough my wife is asking what I spilled in the garage.
I am not disparaging UPR as a company at all. Can’t say whether it’s design in the product or hoses that are permeable to vapors or what is causing the smell. All I have is results confirmed twice.

Curious about others thoughts and experiences with catch cans. Mine is not going back. In fact, first person to pm and pay for shipping can have it.

I have the UPR single valve catch can and we haven't ever noticed any fuel odors in either garage or anywhere near the Bronco Raptor. It's an enclosed loop system, guessing there may be some leak, but you've done your due diligence. I'm going to pay closer attention now, maybe my sniffer just isn't as good as yours.

I have the same one. It’s not a subtle smell at all so I doubt it’s something you’re missing due to lack of sniffer quality. I found a discussion in an old eco boost forum mentioning a persistent smell from catch cans, not any specific manufacturer. They all came back to blaming it on hoses that were excessively permeable to the vapors involved. On mine, it appears everything is intact, all fittings clicked in tight. I agree it likely leaking vapor somewhere in the system. I’m just not particularly interested in chasing down the source since just removing it solves the issue. I may just reach out to UPR and see what they say.
Easiest route is just to move on.
