Hpop fitting oring

Anyone know what the size is for the orings on fittings at pump and fittings on head, think they are same oring but not sure. Had one blow out and figured might as well replace them all just to be sure. Seen the kit a diesel orings but have a Parker and Grainger store nearby so if could pick up locally and not wait that would be better.

Thanks

I think it's a 6 orb on the pump, and 5 orb in the heads. Not sure of exact o ring size though, but I'd assume they're different.

Thanks, just found couple other threads that say what you did. Gonna stop by Parker tomorrow and see if can get some if not will just order a kit and wait.

-906 and -905 get them in viton
