I just recently went to Orielys auto parts for glow plugs for my 1989 f350 idi. The guy behind the counter said he had 8 in stock and that they were AUTOLITE's. I took them home and installed them. The truck started once. Then the whole GP relay clicking thing started and NO start. Started reading online about AUTOLITE GP's. Proceeded to Remove the autolites and ordered MOTORCRAFT at Oriely's. A lot of these parts guys don't tell you that there is other/ better parts available, YOU HAVE TO ASK !!! This has become regular practice for me (Although I didn't with the glow plugs), because I initially though Autolite was connected to FORD , which I found out recently, They are not-Autolite is owned by FRAM. The autolite/ford connection ended years ago, from what I've read. Never knew that.
Anyways, I got my Motorcraft GP's @ $3 more each, installed them and now she fires right up, every time. I also installed a new voltage regulator and once again, asked if they offered a better one. The first one was Chinese made for $19, he went in back and brought out a motorcraft for $23, 3 times as heavy as the Chinese one. You have to ask !!!-inferior parts suck.
