I need to remove the fuel distributor from my car. There are nine connectors and I have removed eight but the last one has me beat. This is a nut holding on a fuel line so an open ended wrench is needed. The problem is there is no room to get an open ended wrench on it. Is there any alternative? I've seen these locking plier type things at the hardware store. I need something with long slim jaws that will lock and not slip.
I desperately need to finish this job this weekend. I've already made two trips (had to walk miles) to the local hardware store to buy tools for this job.
