Looks to be high quality O-ring set
I am going to do the inj cups on my 02 F250, and was ordering parts as I had the extra $$$....But now I have shoulder surgery in 3 days, so the project is delayed a couple months ...Going off of RiffRaffs reputation, I have NO fear of the quality of ANYTHING I buy from them...As soon as I am able, I will order the inj. cups and rent the tool to do the job....Thanks to Riffraff for renting the tools, and for being the best design and quality tools available...They have ALL of my future business, as well as those I know that need parts for their trucks....

Replacement o-rings!
I had to do the injector cup job and replacing the o-rings was part of the procedure. These fit quite well.
I noticed that when the orange and pink o-rings came in contact with brake parts cleaner, they became slightly discolored (black) --- I recommend you keep these o-rings away from contact with part cleaner. -
great product.
Perfect fit, used a dental pick to lift the old ones up enough to cut them.
And for what it's worth my truck took almost 120 miles before it cleared up and was running smooth again, I did the injector cup at the same time though.
