A great surprise was that they included the bottom o rings for ls3 injectors, which isn’t stated in the description. Saving me some money but I get to return the bottom o rings I purchased separately. Great quality parts.

Worked good on my ls1 with ls3 injectors. I originally ordered the wrong ones and they were too short and were prone to leaking. I dodge the bullet of my car burning down and got these

One of the slides/pictures it says that it’ll fit from a ls1 fuel rails to ls3 injectors, they do not fit they ended up being way to tall so the information isn’t very accurate, I did end up changing up other thing around the fuel rail to make them fit, just installed them today so far they haven’t leak or shown any signs of leaking but it’ll still keep an eye out for any due to them being a little sketchy.
