fuel gaskets and vaccum lines?

I have found these kits (9 O-rings) to replace the o-rings/gaskets in/near the fuel rails.

Amazon.com: ACDelco 217-440 O-Ring: Automotive Amazon.com: ACDelco 217-440 O-Ring: Automotive

http://www.autozone.com/autozone/par...entifier=79645

Are there more seals as part of the fuel system in this area? If so, does anyone have any part numbers for a kit, or a website?

Also, all the vaccum lines snapped when I was removing my plenum and the runners due to age. Does anyone have part numbers or a website for replacements? I know everyone will say "fab your own." I'm just wondering if stock or near-storck replacements are available.

Thanks!
Bill

RockAuto.com has stock replacement vac lines, I believe.

But in all seriousness, if you make your own (and by make I simply mean buy some 1/4" or 3/8" rubber fuel line and cut it to length) it will be cheaper and more durable. (the fuel line has thicker walls than what is typically sold as vacuum line).

vetteoz, thanks for the site.

RedLeader, I checked out RockAuto before posting and could not find vaccum lines. If you see them on there, could you send me a link?

I was consdering getting 1/4 or 3/8 silicone line, but I'm not sure which of the two sizes I need. What would be better, silicone line or fuel line?

Re: fuel gaskets and vaccum lines?

I couldn't find anything on there either, my bad.

It's up to you, I believe both will hold up about equally. The fuel line will have a thicker sidewall, but in terms of price I think it's all about the same.
