Jason, I will take a stab at it, Personally, I don't replace the accumulator unless I can put the car on the rack. I don't want the problem of leverage or the right positioning. Plus I'm 220 LB's and 6 foot tall. Then I made two wrenches to break the lines loose. The are extra long handle 14mm and maybe 19mm. The original factory warranty manual shows that it's . 6 hour. This is what Delorean Company as I understand it would be reimbursed the dealer to replace unit. The actual R & R shop manuals may show 1 hour. Drain the lines, prepare, find the right wrenches, tug on them a little to see if what they are using is good enough. I would explain to the mechanic to please be careful not to twist the upper connector. So, I wouldn't push them to hard on the time and if they said and hour. and everything went OK, then good. John Hervey << Does any one have a step by step guide as to how to install the Fuel Accumulator? Any pictures? The reason is I will have to bring my D into a repair shop locally who would be billing me per hour and if I show them that this should not take longer than "1/2 hour" I have some recourse if they claim that it took them more time than this to do or screwed something up. Also I would like to advise them of all they need to know about the car, dangers, warnings etc.... before they start work on it. Thanks everyone! Jason >>
