fuel pressure regulator o-rings sizes?

canadianwheeler said:

I have a leak on my fuel pressure regulator and it seems to be just the o-ring on the vacuum side. My auto parts store will only sell me the whole unit with the o-rings for $130 and not the o-rings on there own. Does anyone know the sizes of the o-rings or if i can by them on there own? I heard they might be included in the injector o-ring kits?

What year?

RENIX (1987-1990) uses the same size O-ring as the top of the fuel injectors, that's why the OEMR kits have the "odd" ring in them. I'm not sure about later models (1991-2001.)
