Denso 720's seals question. Need help

[stockfornow]

I have Denso 720's with stock fuel rail. Well, when I got them, I only got the o-ring and the rubber spacer... Well, the o-ring goes to the into the fuel rail, and the rubber spacer sits there between the fuel rail and the top or the injector. I'm wondering what kind of o-ring goes on the bottom of the injector, where it goes into the head? Can I go to the NAPA or something and get the same o-ring seal as the one on top of the injector, or is it a completely different type of seal. Any pics would be really great.

Thanks, for any help. I just need to get it figured out ASAP.

You need the lower injector insulators. They are different than the upper seals and the rubber spacer. Here is a picture I got from MachV.com.

Here is another link to SBR's lower o-ring kit.

Thank you very much. Excatly what I needed. Also at SBR website it says that it's a mitshu part. Can I just go to a dealership and get it there?

I remember when I was trying to install mine with stock o-rings they 'd still be kinda loose after the fuel rail bolts were tightened. I ended up with o-rings from an '80s turbo Chrysler. I used two of those on each injector and everything fit snug and formed a good seal. Check your local Home Depot/Lowes too. They have a section with rubber insulators.

On a side note.. Oleg, Russian? I 'm Constantine btw
