While I was away at school, my Delorean sat with about a half tank of gas. This was probably since around November/December, a little bit over nine months (I originally had arranged for someone to drive the car every two weeks but that fell through after I'd already left for school and, unfortunately, I never had a chance to drain the tank or put a fuel stabilizer like Stabil in it). Today I removed the baffle in the luggage compartment and took the fuel sending unit out and the gas itself looks alright, it hadn't turned into tar or anything (although I guess that doesn't really mean much as there could be sludge at the bottom of the tank). I think I read somewhere on these boards that gas can sit around for at least six months without getting contaminated and screwing the fuel line. I was wondering if this was a conservative estimate; do you guys think that my car has been sitting long enough to justify doing the fuel tank drain/clean at all, or is it unnecessary? And if I do decide to go through with the draining/cleaning process, (and I'm using the DMCNews thread at http://autos.groups.yahoo.com/group/dmcnews/message/32116 for my reference) how exactly do I "go after it" with my Berryman's B12? I understand the whole process fine up until the point where I have to clean the tank through the 3" fuel sending unit hole. I can't really fit my hand through it. Any advice would be much appreciated. Thanks.
