If you are looking to replace them , they can be found in a hardware store like Home depot . I took vernier calipers and measure the diameter on the injector , and then the hole diameter in hte intake and just went to the store and purchased the o-rings I needed from the measurements that I took and they worked great .

Really? That's good to hear. I bought some replacement O-rings from Home Depot also but I was concerned that the rubber was not the same as the originals and the ones from Home Depot might not stand up to the fuel/heat.

If yours are working fine though I guess they're ok then.

Most you buy at hardware stores are not going to hold up to the fuel and heat of a motor. The rubber will eventually dry and leak or crack. You can get them at any auto parts stores.

The ones you buy at the hardware store are made of the same material as the ones on all cars EXCEPT cars that come with turbochargers or superchargers from the factory , those are designed to take more heat and have a stronger seal because of the boost .

Well that's good to hear. I had ordered a new set of the new Viton material O-rings because I was afraid the Home Depot ones weren't up to the task. If they truely are the same material as regular automotive O-rings then I guess I'll proceed with my install and I'll have some extras if I need it.

It's funny considering since a lot of cars have this size that when I go to SEVERAL different auto parts stores they don't have it. I even brought one of my old O-rings in with me to show them what I need and they all unanimously said "yeah, we don't have any that small" or something to that effect. Then I had them look it up on their computer for a LS1 V8 and then they say they don't have it again - they're the ones that told me to go to a HARDWARE store instead. Ridiculous.

Seems like all the auto parts stores are good for nowadays is fuzzy dice, license plate frames, gay NOS floormats and APC Eurofag taillights.
/rant off/

Sorry, just had to get that out of my system....

You need to go to a "jobber" auto part store.


Pep & the zone are a bunch of D@^b@$$Es

A regular parts store will know exactly what your talking about.

They usually sell 'em in packs of 12.

yeah, you're right. Those "jobber" kinda auto stores are few and far between sometimes. Seeing that you are in Chicago where would you recommend for next time? I'm in the NW Burbs in Palatine. Anything decent around here anywhere?? Thanks.
