I would not have done this successfully without your help and suggestions. At one point, I had so many tools on the work bench trying to remove the defective FPR (fuel pressure regulator) for ‘89 Carrera 3.2 cabriolet without any luck. In my frustration, I decided to seek help and guidance from this forum and that was a very good decision.
I went to bed last night with no sight of success in the horizon and a very disappointing day. Actually it has been 2 days since I started to remove the FPR and failed miserably. After breakfast this morning, I went to HF to buy more tools and cut them to fit for my needs. While I was preparing my cutting tool, something just pop out in my mind.
Went back to the car and took a close look. Nobody even mentioned this trick and procedure so far. When you are desperate, you will try anything to save your neck.
This was my first FPR removal and next time around, it would not be a 30-hour debacle by a 30-min. relaxing and fun job. No need for special tools. All I needed were 10, 15, 17, & 19-mm standard open wrenches and piece of string to loosen the stubborn nut. I even contemplated dropping the motor yesterday.
To summarize this experience, you will need about 20~30 mins. to remove a FPR without dropping the motor and cursing because there is an easy and convenient way to tackle this project. Finally, thanks to everyone specially Ivan B. for his guidance and encouragement.
