Im installing a LS6 standard volume pump with my h/c, but I don't have a new O Ring. Do I need a new one or can I resue the old one? The pump is GM #12586665. I got everything from Tick, and they sell an O Ring separate. The "blue" one for 98-02 Fbodies their description says. Its GM #12557752. Is that the one I will need?

 

NEVER reuse a o-ring, it's just not worth it

 

I jut ordered a Melling 295. The pic shows it with two o-rings.... They weren't included?

 

No, none were included

 

Yes, you need the blue o-ring made for F-Bodies.

Call a local GM Dealer to see if they have one in stock if you don't want to wait for shipping and buy 2 or 3, just in-case you mess up on the install. Good Luck!
