Negative Trader Feedback - general used part rant

i bought a set of fuel rails from someone on here, and thanks to the fucktard i had to pull these things 3 times... i threw them on and didnt look much closer than to make sure they fit, put them on and prime the FP... fuel goes eveywhere, the o ring wasnt sealing due to bent mount tabs. then prime again and i hear fuel dripping... look at the front fittings and NO teflon or ANY sealant on the NPT fittings, think no prob ill take them apart and tape them.... NOOOOO no sealant was used but he did make sure to gorilla piss tighten the FUCk out of them. so after doing the front 2 i prime again and what do you know the back leaks too... so after 2 hour fucking with these rails i finally got the car started. i cant find his SN but i just wanted to give a general warning to everyone.... when you get something used PLEASE make sure you check the parts over before you install them, it will save a LOT of time and headache.
