cold start valve leaking

its leaking at the rail, on top of the nut, through the line. the tiny little o-ring inside is pretty beat up, do I have to buy a whole new injector to get the o-ring though?

thanks in advance

Re: cold start valve leaking

You can go to any parts store and pick up a pack of different size o-rings and use the one out of the pack that looks closest to the original size. Thats what i did, and now i got a lot of extra orings that i can use for what ever projects may need them. But then again you might just be able to go buy the right specific o ring. GOOD LUCK

I got the chance to go to the parts store yesterday and we went through the available o-rings but didn't find anything very close to the cold start valve's thickness or diameter. I'll call up the dealership tomorrow and see what they say.
