Hey guys i am going to install my 72#'s but i need a part first. I got O rings but they are not the same. I need the O rings that are on the ends of the injectors shown here.

The black O ring on top and the bottom. Does anyone know where i can get those?

home depot..thats were i got mines

call up rc engineering,

do you have their # by any change? And how would you found those at home depot?

nah i dont, try googlin it.

Look on the MSD website, you will get a part number then order them at SummitRacing.com. The bottom one isn't as important as the top. I know a guy that didn't run the bottom rings as the injector seals on the large rubber washers on the intake manifold.

I looked but i didn't seem to find them. I have the small O rings but when i slide it into the rail it's WAY to loose.

try a auto store or anyone that carries ac delco parts- gm has similar injectors, o-rings are the same- 93 and up pontiac grandam
