I just got through replacing my fuel filter (suspected to be clogged due to a failed accumulator) and ran into some problems. I was replacing an OEM Bosch filter with another OEM Bosch filter, both of which I obtained from a full-service DeLorean vendor (so, it should work). I got the new filter on and the car would not start. When jumping the cold start valve, the car would run, so I know that some fuel was getting past, but apparently not enough to get to the main injectors. Before I hooked up the pressure gauge, I noticed that the 90-degree adapter on the fuel filter inlet was completely inserted into the filter, which was not the case on the old filter (and IIRC, not the case on the filter before that). I took everything apart and discovered that when this 90-degree adapter finds its way completely into the filter, fuel is choked by the inner bulb of the filter canister. A few photos to illustrate the problem: http://tinyurl.com/l89vy Another new filter (Bosch OEM) solved my problem and after addressing a fuel leak on that pesky rigid line-to-90 degree adapter connection (why is that connection always so difficult?!), I'm back on the road. I don't know why the adapter had to be fully inserted on the bad filter in order to tighten down. I did a search to see if anyone else had this problem and apparently I'm not alone. I found Dave's post below and another post reporting that there's a Purolator filter that solves the inner-bulb problem and works fine. I guess I can't remember posts from 8 years ago. Bottom line: you have to leave enough space between the adapter and the inner bulb in the fuel filter to let the fuel flow, or else your car isn't going to run. I used a couple of wraps of Teflon tape to ensure there were no leaks and just kept it away from the edge that would be inside the filter.
