I didn't think it was all that bad... I downloaded the PDF file from this site... cutting the allen wrench with my dremel was a breeze... for the replacement bolt I just switched with a bolt from on top of the intake that was holding down a bracket... same size length and thread and used that to replace the rear allen head bolt. The circlip was easy getting off a lil more difficult getting back on the new FPR as it seemed to sit a lil higher than the old one... prolly the newness of the new o-ring. Whole thing took 20-25mins.
Overall, changing MAF, fuel filter, and FPR took hour and a half, tops.
Old FPR?: it just looked ooold n worn out, no visible damage or deformity
