Re: [DML] Fuel Accumulator

I just changed my accumulator a couple of weeks ago, and it was a 
royal pain!  I also had the problem of trying to fit and get 
leverage on that 17 mm nut on the accumulator (from the hard line) 
next to the 19mm nut.  I ground down one side of the stubby wrench 
so that the wrench would fit between the 17 and 19 mm nuts.  It did 
fit, but I could still not get leverage to loosen the nut.

What I did next is probably not recommended, but I did it anyway.  
To loosen the stubborn 17 mm nut, I took a flat bladed long 
screwdriver and a hammer, and tapped the edge of the nut with the 
screwdriver to loosen it.  Once the frozen nut broke free, then my 
ground-down stubby wrench worked fine to finish disconnecting it.  I 
then dropped it out of the frame and easily removed the rest of the
