92 Civic LX with 240,000 miles..all stock.

I'm smelling fuel inside the car while I take my hour long drive to work every morning, smelled like it's coming from the vents. I checked the fuel lines under the hood from the fuel filter to under the car, no leaks.
There is alittle bit of dirt sticking on the fuel rod where the injectors are, and when I swiped and sniffed my finger on the fuel rod(where the dirt is) I smelled fuel. So I need to replace the O-Rings located on the top of the injectors and you bolt the fuel rod down.

BUT I'm having an issue finding the exact name of the O-rings for the fuel injectors. There are maybe 3 different sets of O-rings for those injectors, I'm not trying to buy them all, just 1 set(for now).

I looked on a couple Honda Parts sites but it looks pretty confusing because I don't know how small the O-Rings I need are, and other sites just BLOW UP the pictures of the rings and make them look huge.
Any advice or direction would be great!

Thank you in advance!

BTW, couple months ago I brought a headgasket kit, and the rings I need now were included, so I installed the rings BUT it was a VERY TIGHT FIT when I bolted the fuel rod down....SO TIGHT I had to smush each ring in little-by-little as I bolt the fuel rod down little-by-little.

 

Order from a dealer, or take one of the injectors out, take to a parts store, and find a ring that fits. If you get generic rings, make sure they are rated for gasoline.

To install, unplug all 4 plugs and pull the rail off. Pull an injector out, take the old ring off and put a new one on. Do not use metal tools to remove the old one. Put oil (motor oil will work) onto the end of the injector and ring and carefully push it into the hole in the fuel rail. Do this with all 4, then put the fuel rail with injectors already in place onto the intake.

 

Did you check the fuel pressure regulator on the fuel rail? That's where mine was leaking from. Could smell it through the vents and around the hood of the car. Luckily I caught it before it began really dripping fuel all onto a hot engine! Might want to look into that too.

and here's a link to College Hills Honda parts.. it's #6 for the fuel pressure regulator, and #12 for the o-rings, there are three different o-rings though.
