Noticed that when i arrive with my MiniCAb 2001, there is always a small pudding of gas on the pave just below the gas cap... the gas seems to come from the cap key slot... the cap seal proprely because when i unscrew it, i can ear the sheeesh (air coming in or out). Are the gas tank under pressure ? Cannot understand how the gas can be forced out from the key slots ... My Mitsubishi has been bought 3 days ago.
Hi Robert, I know this is an old post, but I'm having the same issue with my 1994 Minicab. By chance, did you ever solve this issue and if so did you determine the cause? My novice theory is that mine has to do with the fuel pump or some other part of the fuel system (vacuum?) that is causing negative pressure and pushing gas back toward the filler. Best, Shawn
Mine was leaking also on my ‘92 minicab. I just purchased a Stant 10806 cap from Oreilly’s for $8.50. It fits well and is snug. It fits a long list of 80s and early 90s Japanese vehicles. I haven’t driven it yet. If you look up for a 83 Mitsubishi Montero, there will also be a locking cap if you need that.
Hey @ocscott5, thanks for the tip! That looks spot on, and checked and I can get it from my local O'Reilly tomorrow. In the meantime, I had put another gasket on there to double stack to keep the cap as tight as possible, which stopped the leak. But doesn't seem like the longterm fix I really want or need. Hoping this Stant does the trick. Appreciate it!
