There is also a green one.... I think i had a Blue one, but when I replaced it, the dealer sold me a Green on. I am not sure what the differences is either.

depends on oil pickup tube style. the blue one is mainly used in ls1 f-body cars and vettes. don't know on the trucks, they might be different.

When i got mine from the dealer i believe it was blue. I just ordered another one cuz i think mine got hosed. My oil pressure is slowly starting to decrease as time goes by. hope its not the oil pump. I just replaced it about a year and a half ago..... Oh, I also read somewhere that there is a thicker oring that is recommended for our application.

I believe that is the blue one. I just measured it, it is 0.137" thick.

I used this one: 12557752

Just make sure you tighten the pickup tube before the bolts that mount the pump or you risk damaging the o-ring and life will not be good for a little while.

Truck pans use the green o-ring, which has a larger cross-section.
