cold start Valve Assy - O-ring Help

Hey guys,

87, L98/350/Tpi
had a leak at the back of the fuel rail, where the Cold Start Valve assy attaches to the fuel rail. Helms shows O-ring seal 104. Checked around at Chevy dealers and no luck here in WA, Did reach Superior, and they can order the set for me, but will be a week or so till i get it. Check Shucks, Napa, lowells, Depot, and no luck.

Anyone had to substitute the o-rings? or anyone have a spare in good shape that's available...

Thanks

I used 2 small o-rings from a universal o-ring assortment. It worked fine.

Yea I hear ya... just got back from napa and picked up 2 pkgs of universal. When you did it, did you find that the seal around the tip or the OD fit to the rail was best...

I believe this is the correct o-ring size, check here. If it turns out to be wrong, please correct me.

The rings I used had a snug fit inside the yube and had to be stretched over the nipple end.
